  Introduction

  FIG. 1 shows a wireless device 100 having a communication module 110 coupled to a primary antenna 130 and a diversity antenna 140. The communication module 110 (and its components) can be controlled by the controller 120. The communication module 110 includes a transceiver 112 configured to convert between analog radio frequency (RF) signals and digital data signals. To that end, the transceiver 112 includes a digital / analog converter, an analog / digital converter, a local oscillator that modulates or demodulates a baseband analog signal to a carrier frequency, digital samples and data bits (eg, voice or other). Baseband processor or other components that convert between these types of data).

  Communication module 110 further includes an RF module 114 coupled between primary antenna 130 and transceiver 112. Because RF module 114 is physically close to primary antenna 130 to reduce attenuation due to cable loss, RF module 114 can be referred to as a front-end module (FEM). The RF module 114 can perform processing on an analog signal received from the primary antenna 130 of the transceiver 112 or an analog signal received from the transceiver 112 and transmitted via the primary antenna 130. To that end, the RF module 114 may include filters, power amplifiers, band select switches, matching circuits, and other components. Similarly, the communication module 110 includes a diversity RF module 116 coupled between a transceiver 112 and a diversity antenna 140 that perform similar processing.

  When a signal is transmitted to the wireless device, the signal may be received at both primary antenna 130 and diversity antenna 140. Since primary antenna 130 and diversity antenna 140 are physically separated, signals received at primary antenna 130 and diversity antenna 140 have different characteristics. For example, in one embodiment, primary antenna 130 and diversity antenna 140 may receive signals with different attenuation, noise, frequency response, or phase shift. The transceiver 112 can use both signals with different characteristics to determine the data bits corresponding to the signals. In some implementations, the transceiver 112 is selected from among the primary antenna 130 and the diversity antenna 140 based on the characteristics, such as selecting the antenna with the highest signal-to-noise ratio. In some implementations, the transceiver 112 combines the signal from the primary antenna 130 and the signal from the diversity antenna 140 to increase the signal to noise ratio of the combined signal. In some implementations, the transceiver 112 processes signals to perform multiple input / multiple output (MIMO) communications.

  Since diversity antenna 140 is physically spaced from primary antenna 130, diversity antenna 140 is coupled to communication module 110 via a transmission line 135, such as a cable or printed circuit board (PCB) trace. In some implementations, the transmission line 135 is lossy and attenuates the signal received at the diversity antenna 140, after which the signal reaches the communication module 110. That is, in some implementations, gain is applied to signals received at diversity antenna 140, as described below. Gain (or other analog processing such as filtering) can be applied by the diversity receiver module. Since such a diversity receiver module is provided physically close to the diversity antenna 140, it can be referred to as a diversity receiver front-end module.

  FIG. 2 shows a diversity receiver (DRx) configuration 200 that includes a DRx front-end module (FEM) 210. The DRx configuration 200 includes a diversity antenna 140 configured to receive a diversity signal and provide the diversity signal to the DRx FEM 210. The DRxFEM 210 is configured to process the diversity signal received from the diversity antenna 140. For example, the DRxFEM 210 can be configured to filter the diversity signal to one or more active frequency bands, for example, as indicated by the controller 120. In other examples, the DRxFEM 210 can be configured to amplify the diversity signal. To that end, DRxFEM 210 may include filters, low noise amplifiers, band select switches, matching circuits and other components.

  DRxFEM 210 transmits the processed diversity signal to a downstream module, such as diversity RF (D-RF) module 116, via transmission line 135. The downstream module supplies the further processed diversity signal to the transceiver 112. Diversity RF module 116 (and transceiver in some implementations) is controlled by controller 120. In some implementations, the controller 120 can be implemented in the transceiver 112.

  FIG. 3 illustrates that, in some embodiments, a diversity receiver (DRx) configuration 300 can include a DRx module 310 with multiple paths corresponding to multiple frequency bands. The DRx configuration 300 includes a diversity antenna 140 configured to receive a diversity signal. In some implementations, the diversity signal may be a single band signal that includes data modulated into a single frequency band. In some implementations, the diversity signal can be a multi-band signal (also referred to as an inter-band carrier aggregation signal) that includes data modulated into multiple frequency bands.

  The DRx module 310 has an input that receives the diversity signal from the diversity antenna 140 and an output that provides the processed diversity signal to the transceiver 330 (via the transmission line 135 and the diversity RF module 320). The input of the DRx module 310 is supplied to the input of the first multiplexer (MUX) 311. The first multiplexer 311 includes a plurality of multiplexer outputs. Each multiplexer output corresponds to a path between the input and output of the DRx module 310. Each path may correspond to each frequency band. The output of the DRx module 310 is given by the output of the second multiplexer 312. The second multiplexer 312 includes a plurality of multiplexer inputs. Each multiplexer input corresponds to one of the paths between the inputs and outputs of the DRx module 310.

  The frequency band may be a cellular frequency band such as a UMTS (Universal Mobile Telecommunications System) frequency band. For example, the first frequency band may be UMTS downlink or “Rx” band 2 from 1930 MHz (MHZ) to 1990 MHz, and the second frequency band may be UMTS downlink or “Rx” band 5 from 869 MHz to 894 MHz. Other downlink frequency bands may also be used, such as those described below in Table 1 or other non-UMTS frequency bands.

  In some implementations, the DRx module 310 includes a DRx controller 302. The DRx controller 302 receives a signal from the controller 120 (also referred to as a communication controller), and selectively activates one or more of a plurality of paths between the input and the output based on the received signal. In some implementations, the DRx module 310 does not include the DRx controller 302 and the controller 120 selectively selectively activates one or more of the multiple paths.

  As noted herein, in some implementations, the diversity signal is a single band signal. That is, in some implementations, the first multiplexer 311 is a single pole that routes the diversity signal to one of a plurality of paths corresponding to the frequency band of the single band signal based on the signal received from the DRx controller 302. / Multi-throw (SPMT) switch. The DRx controller 302 can generate a signal based on the band selection signal received by the DRx controller 302 from the communication controller 120. Similarly, in some implementations, the second multiplexer 312 can route a signal from one of a plurality of paths corresponding to a frequency band of a single band signal based on a signal received from the DRx controller 302. It is.

  As noted herein, in some implementations, the diversity signal is a multiband signal. That is, in some implementations, the first multiplexer 311 transmits the diversity signal to two or more of a plurality of paths corresponding to two or more frequency bands of the multiband signal based on the divider control signal received from the DRx controller 302. It is a band divider for routing. The function of the signal divider can be implemented as an SPMT switch, a diplexer filter, or some combination thereof. Similarly, in some implementations, the second multiplexer 312 converts the signals from two or more of the plurality of paths corresponding to two or more frequency bands of the multiband signal into the combiner control signal received from the DRx controller 302. A signal combiner that couples based on. The function of the signal combiner can be implemented as an SPMT switch, a diplexer filter, or some combination thereof. The DRx controller 302 can generate a divider control signal and a combiner control signal based on the band selection signal received by the DRx controller 302 from the communication controller 120.

  That is, in some implementations, the DRx controller 302 selectively activates one or more of the multiple paths based on a band selection signal received by the DRx controller 302 (eg, from the communication controller 120). Composed. In some implementations, the DRx controller 302 selectively activates one or more of the multiple paths by transmitting a divider control signal to the signal divider and a combiner control signal to the signal combiner. Configured as follows.

  The DRx module 310 includes a plurality of band pass filters 313a to 313d. Each one of the bandpass filters 313a to 313d is provided along a corresponding one of the plurality of paths, and filters a signal received by the bandpass filter to the one corresponding frequency band of the plurality of paths. Configured as follows. In some implementations, the bandpass filters 313a-313d are further configured to filter signals received at the bandpass filters to the downlink frequency subband of the one corresponding frequency band of the plurality of paths. . The DRx module 310 includes a plurality of amplifiers 314a to 314d. Each one of the amplifiers 314a to 314d is provided along a corresponding one of the plurality of paths, and is configured to amplify a signal received by the amplifier.

  In some implementations, amplifiers 314a-314d are narrowband amplifiers configured to amplify signals in the corresponding frequency band of the path in which the amplifier is provided. In some implementations, the amplifiers 314a-314d can be controlled by the DRx controller 302. For example, in some implementations, amplifiers 314a-314d each include an enable / disable input and are enabled (or disabled) based on an amplifier enable signal received at the enable / disable input. The amplifier enable signal can be transmitted by the DRx controller 302. That is, in some implementations, the DRx controller 302 transmits an amplifier enable signal to one or more of the amplifiers 314a-314d, each provided along one or more of the plurality of paths, to thereby It is configured to selectively activate one or more. In such an implementation, rather than being controlled by the DRx controller 302, the first multiplexer 311 is a signal divider that routes the diversity signal to each of the multiple paths, and the second multiplexer 312 is from each of the multiple paths. The signal combiner can be a signal combiner that combines the two signals. However, in implementations where the DRx controller 302 controls the first multiplexer 311 and the second multiplexer 312, the DRX controller 302 also enables (or disables) certain amplifiers 314 a-314 d, for example, to save battery power. You can also.

  In some implementations, amplifiers 314a-314d are variable gain amplifiers (VGA). That is, in some implementations, the DRx module 310 includes a plurality of variable gain amplifiers (VGAs), each one of which is provided along a corresponding one of a plurality of paths, and a signal received at the VGA. Is amplified by a gain controlled by the amplifier control signal received from the DRx controller 302.

  The gain of the VGA can be bypassable, variable in steps, and continuously variable. In some implementations, at least one of the VGAs includes a fixed gain amplifier and a bypass switch that can be controlled by an amplifier control signal. The bypass switch (in the first position) can allow a signal to bypass the fixed gain amplifier by closing the line between the input of the fixed gain amplifier and the output of the fixed gain amplifier. . The bypass switch (in the second position) allows the signal to pass through the fixed gain amplifier by opening the line between the input and output. In some implementations, the fixed gain amplifier is disabled when the bypass switch is in the first position, and is otherwise reconfigured to match the bypass mode.

  In some implementations, at least one of the VGAs includes a step variable gain amplifier configured to amplify a signal received at the VGA by a gain of a plurality of set amounts indicated by the amplifier control signal. . In some implementations, at least one of the VGAs includes a continuously variable gain amplifier configured to amplify a signal received at the VGA with a gain proportional to the amplifier control signal.

  In some implementations, amplifiers 314a-314d are variable current amplifiers (VCA). The current drawn by the VCA can be bypassable, step variable, continuously variable. In some implementations, at least one of the VCAs includes a fixed current amplifier and a bypass switch that can be controlled by an amplifier control signal. The bypass switch (in the first position) can allow a signal to bypass the fixed current amplifier by closing the line between the input of the fixed current amplifier and the output of the fixed current amplifier. . The bypass switch (in the second position) allows the signal to pass through the fixed current amplifier by opening the line between the input and output. In some implementations, the fixed current amplifier is disabled when the bypass switch is in the first position, and is otherwise reconfigured to conform to the bypass mode.

  In some implementations, at least one of the VCAs is a step variable current amplifier configured to amplify a signal received at the VCA by extracting a single set of currents indicated by the amplifier control signal. including. In some implementations, at least one of the VCAs includes a continuously variable current amplifier configured to amplify a signal received at the VCA by drawing a current proportional to the amplifier control signal.

  In some implementations, amplifiers 314a-314d are fixed gain, fixed current amplifiers. In some implementations, amplifiers 314a-314d are fixed gain, variable current amplifiers. In some implementations, amplifiers 314a-314d are variable gain, fixed current amplifiers. In some implementations, amplifiers 314a-314d are variable gain, variable current amplifiers.

  In some implementations, the DRx controller 302 generates the amplifier control signal (s) based on the quality of service metric of the input signal received at the input. In some implementations, the DRx controller 302 generates the amplifier control signal (s) based on the signal received from the communication controller 120. The amplifier control signal may further be based on a quality of service (QoS) metric of the received signal. The QoS metric of the received signal may be based at least in part on the diversity signal received at diversity antenna 140 (eg, the input signal received at the input). The QoS metric of the received signal may further be based on the signal received at the primary antenna. In some implementations, the DRx controller 302 generates the amplifier control signal (s) based on the QoS metric of the diversity signal without receiving a signal from the communication controller 120.

  In some implementations, the QoS metric includes signal strength. In other examples, the QoS metric may include a bit error rate, data throughput, transmission delay, or any other QoS metric.

  As described herein, the DRx module 310 receives the diversity signal from the diversity antenna 140 and the output that provides the processed diversity signal to the transceiver 330 (via the transmission line 135 and the diversity RF module 320). And have. Diversity RF module 320 receives the processed diversity signal via transmission line 135 for further processing. In particular, the processed diversity signal is split or routed into one or more paths by diversity RF multiplexer 321. In the path, the divided or routed signals are filtered by the corresponding band-pass filters 323a to 323d and amplified by the corresponding amplifiers 324a to 324d. The outputs of the amplifiers 324 a to 324 d are given to the transceiver 330.

  Diversity RF multiplexer 321 can be controlled by controller 120 (either directly or through an on-chip diversity RF controller) to selectively activate one or more of the paths. Similarly, amplifiers 324a-324d can also be controlled by controller 120. For example, in some implementations, each of the amplifiers 324a-324d includes an enable / disable input and is enabled (or disabled) based on an amplifier enable signal. In some implementations, amplifiers 324a-324d amplify the received signal at the VGA with a gain controlled by an amplifier control signal received from controller 120 (or an on-chip diversity RF controller controlled by controller 120). It is a variable gain amplifier (VGA). In some implementations, amplifiers 324a-324d are variable current amplifiers (VCA).

  By adding a DRx module 310 to the receiver chain that already contains the diversity RF module 320, the number of bandpass filters in the DRx configuration 300 is doubled. That is, in some implementations, the bandpass filters 323a-323d are not included in the diversity RF module 320. Rather, the band pass filters 313a-313d of the DRx module 310 are used to reduce the strength of the out-of-band blocker. Further, the automatic gain control (AGC) table of the diversity RF module 320 is shifted to reduce the amount of gain provided by the amplifiers 324a to 324d of the diversity RF module 320 by the amount of gain provided by the amplifiers 314a to 314d of the DRx module 310. Can do.

  For example, if the DRx module gain is 15 dB and the receiver sensitivity is −100 dBm, the diversity RF module 320 has a sensitivity of −85 dBm. When the closed-loop AGC of diversity RF module 320 becomes active, its gain automatically drops by 15 dB. However, both the signal component and the out-of-band blocker are received and amplified by 15 dB. That is, the 15 dB gain drop of diversity RF module 320 may be accompanied by a 15 dB increase in its linearity. In particular, the amplifiers 324a-324d of the diversity RF module 320 can be designed such that the linearity of the amplifier increases with decreasing gain (or increasing current).

  In some implementations, the controller 120 controls the gain (and / or current) of the amplifiers 314a-314d of the DRx module 310 and the amplifiers 324a-324d of the diversity RF module 320. As in the example herein, the controller 120 is responsive to a certain amount of gain provided by the amplifiers 314a-314d of the DRx module 310 being increased by a certain amount provided by the amplifiers 324a-324d of the diversity RF module 320. Gain can be reduced. That is, in some implementations, the controller 120 converts the downstream amplifier control signal (for amplifiers 324a-324d of diversity RF module 320) to the amplifier control signal (for amplifiers 314a-314d of DRx module 310). Based on and configured to control the gain of one or more downstream amplifiers 324a-324d coupled to the output (of DRx module 310) via transmission line 135. In some implementations, the controller 120 also controls the gain of other components of the wireless device, such as an amplifier in a front end module (FEM), based on the amplifier control signal.

  As noted herein, in some implementations, bandpass filters 323a-323d are not included. That is, in some implementations, at least one of the downstream amplifiers 324a-324d is coupled to the output (of the DRx module 310) via the transmission line 135 without passing through the downstream bandpass filter.

  FIG. 4 illustrates that, in some embodiments, the diversity receiver configuration 400 can include a diversity RF module 420 with fewer amplifiers than the diversity receiver (DRx) module 310. Diversity receiver configuration 400 includes diversity antenna 140 and DRx module 310 described herein with reference to FIG. The output of the DRx module 310 passes through the transmission line 135 to the diversity RF module 420. Diversity RF module 420 differs from diversity RF module 320 of FIG. 3 in that diversity RF module 420 of FIG. 4 includes fewer amplifiers than DRx module 310.

  As noted herein, in some implementations diversity RF module 420 does not include a bandpass filter. That is, in some implementations, one or more amplifiers 424 of diversity RF module 420 need not be band specific. In particular, diversity RF module 420 may include one or more paths. Each path includes an amplifier 424 that is not mapped one-to-one to the path of the DRx module 310. The mapping of such paths (or corresponding amplifiers) can be stored in the controller 120.

  Accordingly, DRx module 310 may include a fixed number of paths, each corresponding to a frequency band, while diversity RF module 420 may include one or more paths that do not correspond to a single frequency band.

  In some implementations (shown in FIG. 4), diversity RF module 420 includes a single wideband or tunable amplifier 424 that amplifies the signal received from transmission line 135 and outputs the amplified signal to multiplexer 421. Including. Multiplexer 421 includes a plurality of multiplexer outputs, each corresponding to each frequency band. In some implementations, diversity RF module 420 does not include any amplifier.

In some implementations, the diversity signal is a multiband signal. That is, in some implementations, the multiplexer 421 converts the diversity signal based on the divider control signal received from the controller 120 into two or more corresponding to two or more frequency bands of the multi-band signal of multiple outputs. It is a signal divider for routing. In some implementations, the diversity RF module 420 can be combined with the transceiver 330 as a single module.

  In some implementations, diversity RF module 420 includes multiple amplifiers, each corresponding to a set of frequency bands. The signal from the transmission line 135 can be supplied to a band divider that outputs high frequency to the high frequency amplifier along the first path and outputs low frequency to the low frequency amplifier along the second path. The output of each amplifier can be provided to a multiplexer 421 that is configured to route the signal to a corresponding input of the transceiver 330.

  FIG. 5 illustrates that in some embodiments, the diversity receiver configuration 500 can include a DRx module 510 coupled to an off-module filter 513. The DRx module 510 may include a packaging board 501 configured to receive a plurality of components and a receiving system mounted on the packaging board 501. The DRx module 510 may include one or more signal paths routed out of the DRx module 510 and made available to system integrators, designers, or manufacturers that support filters for any desired band.

  The DRx module 510 includes a certain number of paths between the inputs and outputs of the DRx module 510. The DRx module 510 includes a bypass path between input and output activated by a bypass switch 519 controlled by the DRx controller 502. Although FIG. 5 illustrates a single bypass switch 519, in some implementations, the bypass switch 519 includes multiple switches (e.g., a first switch located physically close to the input and an output physical switch). Second switch provided near the target). As shown in FIG. 5, the bypass path does not include a filter or amplifier.

  The DRx module 510 includes a certain number of multiplexer paths including a first multiplexer 511 and a second multiplexer 512. The multiplexer path includes a certain number of on-module paths. This includes a first multiplexer 511, bandpass filters 313 a to 313 d mounted on the packaging substrate 501, amplifiers 314 a to 314 d mounted on the packaging substrate 501, and a second multiplexer 512. The multiplexer path includes one or more off-module paths. This includes a first multiplexer 511, a bandpass filter 513 mounted outside the packaging substrate 501, an amplifier 514, and a second multiplexer 512. The amplifier 514 can be a broadband amplifier mounted on the packaging substrate 501 or can be mounted outside the packaging substrate 501. As described herein, amplifiers 314a-314d, 514 may be variable gain amplifiers and / or variable current amplifiers.

  The DRx controller 502 is configured to selectively activate one or more of the plurality of paths between the input and output. In some implementations, the DRx controller 502 is configured to selectively activate one or more of the plurality of paths based on a band selection signal received by the DRx controller 502 (eg, from a communication controller). . The DRx controller 502 selectively activates the path, for example, by opening or closing the bypass switch 519, enabling or disabling the amplifiers 314a to 314d, 514, controlling the multiplexers 511, 512, or via other mechanisms. Can be. For example, the DRx controller 502 opens or closes a switch along the path (eg, between the filters 313a-313d, 513 and the amplifiers 314a-314d, 514) or substantially increases the gain of the amplifiers 314a-314d, 514. Can be set to zero.

  As described herein, the amplifier that processes the received signal may be a variable gain amplifier (VGA). That is, in some implementations, the DRx module includes a plurality of variable gain amplifiers (VGAs), each one of which is provided along a corresponding one of a plurality of paths, and receives signals received in the VGA. The amplifier control signal received from the DRx controller is configured to amplify with a gain controlled.

  In some embodiments, the gain of the VGA can be bypassable, step variable, continuously variable. FIG. 6 illustrates that in some embodiments, the variable gain amplifier A350 may be bypassable. The variable gain amplifier A350 includes a fixed gain amplifier A351 and a bypass switch A352 that can be controlled by an amplifier control signal generated by the DRx controller A302. Bypass switch A352 can (in the first position) allow a signal that bypasses fixed gain amplifier A351 by closing the line from the input of fixed gain amplifier A351 to the output of the fixed gain amplifier. Bypass switch A352 can (in the second position) open the line between the input of fixed gain amplifier A351 and the output of fixed gain amplifier A351 to pass the signal through fixed gain amplifier A351. In some implementations, the fixed gain amplifier is disabled when the bypass switch is in the first position, and is otherwise reconfigured to match the bypass mode. Referring to the example of FIG. 3, in some implementations, at least one of the VGAs 314a-314d includes a fixed gain amplifier and a bypass switch that can be controlled by an amplifier control signal.

  FIG. 7 illustrates that in some embodiments, the gain of variable gain amplifier A 360 can be step variable or continuously variable. In some implementations, the variable gain amplifier A360 is step variable and the variable gain amplifier is configured with one of a plurality of set points indicated by the digital signal in response to the digital amplifier control signal generated by the DRx controller A302. Amplifies the received signal at the input of A360. In some implementations, the variable gain amplifier A360 is continuously variable and is variable in response to an analog amplifier control signal generated by the DRx controller A302 with a gain that is proportional to the characteristic of the analog signal (eg, voltage or duty cycle). Amplifies the received signal at the input of gain amplifier A360. Referring to the example of FIG. 3, in some implementations, at least one of the VGAs 314a-314d is configured to amplify a signal received at the VGA with a single gain of a plurality of set amounts indicated by the amplifier control signal. Including a step variable gain amplifier. In some implementations, at least one of the VGAs 314a-314d of FIG. 3 includes a continuously variable gain amplifier configured to amplify a signal received at the VGA with a gain proportional to the amplifier control signal.

  In some implementations, the amplifiers 314a-314d of FIG. 3 may be variable current amplifiers (VCA). The current drawn by the VCA can be bypassable, step variable, continuously variable. In some implementations, at least one of the VCAs includes a fixed current amplifier and a bypass switch that can be controlled by an amplifier control signal. The bypass switch (in the first position) can allow a signal to bypass the fixed current amplifier by closing the line between the input of the fixed current amplifier and the output of the fixed current amplifier. . The bypass switch (in the second position) allows the signal to pass through the fixed current amplifier by opening the line between the input and output. In some implementations, the fixed current amplifier is disabled when the bypass switch is in the first position, and is otherwise reconfigured to conform to the bypass mode.

In some implementations, at least one of the VCAs includes a continuously variable current amplifier configured to amplify a signal received at the VCA by drawing a current proportional to the amplifier control signal.

  In some implementations, the amplifiers 314a-314d of FIG. 3 are fixed gain, fixed current amplifiers. In some implementations, amplifiers 314a-314d are fixed gain, variable current amplifiers. In some implementations, amplifiers 314a-314d are variable gain, fixed current amplifiers. In some implementations, amplifiers 314a-314d are variable gain, variable current amplifiers.

  In some implementations, the DRx controller 302 generates the amplifier control signal (s) based on the quality of service metric of the input signal received at the input 311 of the first multiplexer. In some implementations, the DRx controller 302 generates the amplifier control signal (s) based on the signal received from the communication controller 120. The amplifier control signal may further be based on a quality of service (QoS) metric of the received signal. The QoS metric of the received signal may be based at least in part on the diversity signal received at diversity antenna 140 (eg, the input signal received at the input). The QoS metric of the received signal may further be based on the signal received at the primary antenna. In some implementations, the DRx controller 302 generates the amplifier control signal (s) based on the QoS metric of the diversity signal without receiving a signal from the communication controller 120.

  In some implementations, the QoS metric includes signal strength. In other examples, the QoS metric may include a bit error rate, data throughput, transmission delay, or any other QoS metric.

  As described herein, the DRx module 310 of FIG. 3 receives the diversity signal from the diversity antenna 140 and the processed diversity signal to the transceiver 330 (via the transmission line 135 and the diversity RF module 320). And output to give. Diversity RF module 320 receives the processed diversity signal via transmission line 135 for further processing. In particular, the processed diversity signal is split or routed into one or more paths by diversity RF multiplexer 321. In the path, the divided or routed signals are filtered by the corresponding band-pass filters 323a to 323d and amplified by the corresponding amplifiers 324a to 324d. The outputs of the amplifiers 324 a to 324 d are given to the transceiver 330.

  Diversity RF multiplexer 321 can be controlled by controller 120 (either directly or through an on-chip diversity RF controller) to selectively activate one or more of the paths. Similarly, amplifiers 324a-324d can also be controlled by controller 120. For example, in some implementations, each of the amplifiers 324a-324d includes an enable / disable input and is enabled (or disabled) based on an amplifier enable signal. In some implementations, amplifiers 324a-324d amplify the received signal at the VGA with a gain controlled by an amplifier control signal received from controller 120 (or an on-chip diversity RF controller controlled by controller 120). It is a variable gain amplifier (VGA). In some implementations, amplifiers 324a-324d are variable current amplifiers (VCA).

  By adding a DRx module 310 to the receiver chain that already contains the diversity RF module 320, the number of bandpass filters in the DRx configuration 300 is doubled. That is, in some implementations, the bandpass filters 323a-323d are not included in the diversity RF module 320. Rather, the band pass filters 313a-313d of the DRx module 310 are used to reduce the strength of the out-of-band blocker. Further, the automatic gain control (AGC) table of the diversity RF module 320 is shifted to reduce the amount of gain provided by the amplifiers 324a to 324d of the diversity RF module 320 by the amount of gain provided by the amplifiers 314a to 314d of the DRx module 310. Can do.

  For example, if the DRx module gain is 15 dB and the receiver sensitivity is −100 dBm, the diversity RF module 320 has a sensitivity of −85 dBm. When the closed-loop AGC of diversity RF module 320 becomes active, its gain automatically drops by 15 dB. However, both the signal component and the out-of-band blocker are received and amplified by 15 dB. That is, in some implementations, the 15 dB gain drop of diversity RF module 320 may be accompanied by a 15 dB increase in its linearity. In particular, the amplifiers 324a-324d of the diversity RF module 320 can be designed such that the linearity of the amplifier increases with decreasing gain (or increasing current).

  In some implementations, the controller 120 controls the gain (and / or current) of the amplifiers 314a-314d of the DRx module 310 and the amplifiers 324a-324d of the diversity RF module 320. As in the example herein, the controller 120 is responsive to a certain amount of gain provided by the amplifiers 314a-314d of the DRx module 310 being increased by a certain amount provided by the amplifiers 324a-324d of the diversity RF module 320. Gain can be reduced. That is, in some implementations, the controller 120 converts the downstream amplifier control signal (for amplifiers 324a-324d of diversity RF module 320) to the amplifier control signal (for amplifiers 314a-314d of DRx module 310). Based on and configured to control the gain of one or more downstream amplifiers 324a-324d coupled to the output (of DRx module 310) via transmission line 135. In some implementations, the controller 120 also controls the gain of other components of the wireless device, such as an amplifier in a front end module (FEM), based on the amplifier control signal.

  As noted herein, in some implementations, bandpass filters 323a-323d are not included. That is, in some implementations, at least one of the downstream amplifiers 324a-324d is coupled to the output (of the DRx module 310) via the transmission line 135 without passing through the downstream bandpass filter. An example of such an implementation will now be described with reference to FIG.

  FIG. 8 illustrates that in some embodiments, the diversity receiver configuration A600 can include a DRx module A610 with a tunable matching circuit. In particular, the DRx module A610 may include one or more tunable matching circuits provided at one or more of the inputs and outputs of the DRx module A610.

  All of the multiple frequency bands received at the same diversity antenna 140 are unlikely to be ideal impedance matching. To match each frequency band using a compact matching circuit, a tunable input matching circuit A616 is implemented at the input of the DRx module A610 (eg, based on a band selection signal from the communication controller) by the DRx controller A602. Can be controlled. The DRx controller A602 can tune the tunable input matching circuit A616 based on a lookup table that associates multiple frequency bands (or sets of frequency bands) with tuning parameters. Tunable input matching circuit A616 may be a tunable T-type circuit, a tunable π-type circuit, or any other tunable matching circuit. In particular, the tunable input matching circuit A616 may include one or more variable components such as resistors, inductors and capacitors. These variable components may be connected in parallel and / or in series and may be connected between the input of the DRx module A610 and the input of the first multiplexer A311 or the input of the DRx module A610 and the ground voltage. You may connect between.

  Similarly, with only one transmission line 135 (or at least some cables) carrying signals in many frequency bands, it is unlikely that all multiple frequency bands will be an ideal impedance match. A tunable output matching circuit A617 is implemented at the output of the DRx module A610 to match each frequency band using a compact matching circuit (eg, based on a band select signal from the communication controller) by the DRx controller A602. Can be controlled. The DRx controller A602 can tune the tunable output matching circuit A618 based on a lookup table that associates multiple frequency bands (or sets of frequency bands) with tuning parameters. Tunable output matching circuit A617 can be a tunable T-type circuit, a tunable π-type circuit, or any other tunable matching circuit. In particular, the tunable output matching circuit A617 may include one or more variable components such as resistors, inductors and capacitors. These variable components may be connected in parallel and / or in series and may be connected between the output of the DRx module A610 and the output of the second multiplexer A312 or the output of the DRx module A610 and the ground voltage. You may connect between.

The DRx module A710 further includes a tunable output matching circuit A717 at the output of the DRx module A710. The DRx controller A702 can tune each of the tunable matching circuits A716a-A716b, A717 based on a look-up table that associates multiple frequency bands (or multiple sets of frequency bands) with tuning parameters. The tunable matching circuits A716a-A716b, A717 may be tunable T-type circuits, tunable π-type circuits, or any other tunable matching circuits.

  The DRx module A710 is between the input of the DRx module A710 (a first input coupled to the first antenna A740a and a second input coupled to the second antenna A740b) and an output (coupled to the transmission line 135).

  FIG. 10 illustrates one embodiment of a flowchart representation of a method for processing an RF signal. In some implementations (and as detailed below by way of example), Method A 800 is performed by a controller, such as DRx controller 302 of FIG. 3 or communication controller 120 of FIG. In some implementations, Method A800 can be performed by processing logic that includes hardware, firmware, software, or a combination thereof. In some implementations, Method A800 is performed by a processor executing code stored on a non-transitory computer readable medium (eg, memory). Briefly, method A 800 includes receiving a band selection signal and routing the received RF signal along one or more gain control paths to process the received RF signal.

  Method A800 begins at block A810 with the controller receiving a band selection signal. The controller can receive a band selection signal from another controller or a band selection signal from a cellular base station or other external source. The band selection signal can indicate one or more frequency bands in which the wireless device transmits and receives RF signals. In some implementations, the band selection signal indicates a set of frequency bands for carrier aggregation communication.

  In some implementations, the controller tunes one or more tunable matching circuits based on the received band selection signal. For example, the controller can tune the tunable matching circuit based on a look-up table that associates multiple frequency bands (or sets of frequency bands) indicated by the band select signal with tuning parameters.

  In block A820, the controller selectively activates one or more paths of the diversity receiver (DRx) module based on the band selection signal. As described herein, a DRx module is a constant between one or more inputs (coupled to one or more antennas) and one or more outputs (coupled to one or more cables) of the DRx module. It can include a number of paths. The path may include a bypass path and a multiplexer path. The multiplexer path can include an on-module path and an off-module path.

It can be selectively activated by control of one or more multiplexers via control signals and / or coupler control signals, or through other mechanisms. For example, the controller can open or close a switch provided along the path, or set the gain of an amplifier provided along the path to substantially zero.

  In block A830, the controller sends an amplifier control signal to one or more amplifiers each provided along one or more activated paths. The amplifier control signal controls the gain (or current) of the amplifier serving as the transmission destination.

  In some implementations, the controller generates the amplifier control signal (s) based on the input signal quality of service (QoS) metric received at the input. In some implementations, the controller generates the amplifier control signal (s) based on signals received from other controllers and thus signals that may be based on the QoS metric of the received signals. The QoS metric of the received signal is based at least in part on the diversity signal (eg, input received at the input) at the diversity antenna. The QoS metric of the received signal may further be based on the signal received at the primary antenna. In some implementations, the controller generates the amplifier control signal (s) based on the QoS metric of the diversity signal without receiving signals from other controllers. For example, the QoS metric may include signal strength. In other examples, the QoS metric may include a bit error rate, data throughput, transmission delay, or any other QoS metric.

  In some implementations, the controller may also control downstream amplifier control based on the amplifier control signal to control the gain of one or more downstream amplifiers coupled to the output via one or more cables at block A830. Send a signal.

  Example B: Phase shift component

  FIG. 11 illustrates that in some embodiments, diversity receiver configuration B600 may include a DRx module B610 with one or more phase matching components B624a-B624b. DRx module B 610 includes two paths from the input of DRx module B 610 coupled to antenna 140 and the output of DRx module B 610 coupled to transmission line 135.

  In the DRx module B610 of FIG. 11, the signal divider and the band pass filter are implemented as a diplexer B611. Diplexer B611 includes an input coupled to antenna 140, a first output coupled to first amplifier 314a, and a second output coupled to second amplifier 314b. At the first output, diplexer B611 outputs the signal received at the input (eg, from antenna 140) and filtered to the first frequency band. In the second output, the diplexer B611 filters the signal received at the input to the second frequency band and outputs it. In some implementations, the diplexer B611 divides the input signal received at the input of the DRx module B610 into a plurality of signals in each of a plurality of frequency bands propagating along a plurality of paths. , A quadplexer or other multiplexer.

  As described herein, each one of amplifiers 314a-314b is provided along a corresponding one of the paths and is configured to amplify the received signal at the amplifier. The outputs of amplifiers 314a-314b are provided through corresponding phase shift components B624a-B624b before being combined by signal combiner B612.

  The signal combiner B612 includes a first input coupled to the first phase shift component B624a, a second input coupled to the second phase shift component B624b, and an output coupled to the output of the DRx module B610. The signal at the output of the signal combiner is the sum of the signals at the first and second inputs. That is, the signal combiner is configured to combine signals that propagate along multiple paths.

  When a signal is received by the antenna 140, the signal is filtered by the diplexer B611 to the first frequency band and propagates along the first path through the first amplifier 314a. The filtered and amplified signal is phase-shifted by the first phase-shift component B624a and supplied to the first input of the signal combiner B612. In some implementations, the signal combiner B612 or the second amplifier 314b does not prevent the signal from continuing in the reverse direction along the second path through the signal combiner B612. That is, the signal propagates through the second phase shift component B624b, through the second amplifier 314b, and is reflected from the diplexer B611. The reflected signal propagates through the second amplifier 314b, passes through the second phase shift component B624b, and reaches the second input of the signal combiner B612.

  If the phase of the initial signal (at the first input of the signal combiner B612) and the phase of the reflected signal (at the second input of the signal combiner B612) are out of phase, the sum that the signal combiner B612 performs is the signal combiner. The signal at the output of B612 is weakened. Similarly, if the initial signal and the reflected signal are in phase, the sum performed by signal combiner B 612 enhances the signal at the output of signal combiner B 612. That is, in some implementations, the second phase shift component B 624b is configured to phase shift the signal (at least in the first frequency band) so that the initial signal and the reflected signal are at least partially in phase. . In particular, the second phase shift component B 624b is configured to phase shift the signal (at least in the first frequency band) so that the total amplitude of the initial signal and the reflected signal is greater than the amplitude of the initial signal.

  For example, the second phase shift component B 624b phase-shifts the signal passing through the second phase shift component B 624b by −½ times the phase shift introduced by the backward propagation through the second amplifier 314b. It can be configured to reflect from B611 and propagate forward through the second amplifier 314b. In another example, the second phase shift component B 624b causes the signal passing through the second phase shift component B 624b to be half the difference between 360 degrees and the phase shift introduced by back propagation through the second amplifier 314b. It can be configured to be phase shifted, reflected from the diplexer B611, and propagated forward through the second amplifier 314b. In general, the second phase shift component B624b phase-shifts the signal passing through the second phase shift component B624b so that the initial signal and the reflected signal have a phase difference of an integral multiple of 360 degrees (including zero). Can be configured.

  In one example, the initial signal may be 0 degrees (or any other reference phase), propagates backward through the second amplifier 314b, is reflected from the diplexer B611, and propagates forward through the second amplifier 314b. Thus, a phase shift of 140 degrees can be introduced. That is, in some implementations, the second phase shift component B624b is configured to phase shift the signal passing through the second phase shift component B624b by -70 degrees. That is, the initial signal is phase-shifted to −70 degrees by the second phase shift component B 624b, and propagates backward through the second amplifier 314b, forward through the diplexer B 611, and forward through the second amplifier 314b. Is phase-shifted to 70 degrees, and phase-shifted back to 0 degrees by the second phase-shift component B624b.

  In some implementations, the second phase shift component B624b is configured to phase shift the signal passing through the second phase shift component B624b by 110 degrees. That is, the initial signal is phase-shifted to 110 degrees by the second phase shift component B 624b, and propagates backward through the second amplifier 314b, reflected from the diplexer B 611, and forward propagated through the second amplifier 314b. The phase is shifted to 250 degrees, and the phase is shifted to 360 degrees by the second phase shift component B624b.

  At the same time, the signal received by the antenna 140 is filtered to the second frequency band by the diplexer B611 and propagates along the second path passing through the second amplifier 314b. The filtered and amplified signal is phase shifted by the second phase shift component B624b and supplied to the second input of the signal combiner B612. In some implementations, the signal combiner B612 or the first amplifier 314a does not prevent the signal from continuing in the reverse direction along the first path through the signal combiner B612. That is, the signal propagates through the first phase shift component B624a, through the second amplifier 314a, and is reflected from the diplexer B611. The reflected signal propagates through the first amplifier 314a and the first phase shift component B624a and reaches the first input of the signal combiner B612.

  If the phase of the initial signal (at the second input of the signal combiner B612) and the phase of the reflected signal (at the first input of the signal combiner B612) are out of phase, the sum that the signal combiner B612 performs is the signal combiner. The signal at the output of B612 is weakened, and when the initial signal and the reflected signal are in phase, the sum performed by signal combiner B612 enhances the signal at the output of signal combiner B612. That is, in some implementations, the first phase shift component B 624a is configured to phase shift the signal (at least in the second frequency band) so that the initial signal and the reflected signal are at least partially in phase. .

  For example, the first phase shift component B 624a phase-shifts the signal passing through the first phase shift component B 624a by −½ times the phase shift introduced by the backward propagation through the first amplifier 314a. It can be configured to reflect from B611 and propagate forward through the first amplifier 314a. In another example, the first phase shift component B 624a causes the signal passing through the first phase shift component B 624a to be only half the difference between 360 degrees and the phase shift introduced by back propagation through the first amplifier 314a. It can be configured to phase shift, reflect from the diplexer B 611 and propagate forward through the first amplifier 314a. In general, the first phase shift component B 624a is configured such that the signal passing through the first phase shift component B 624a is phase shifted so that the initial signal and the reflected signal have a phase difference of an integral multiple of 360 degrees (including zero). can do.

  The phase shift components B624a to B624b may be mounted as passive circuits. In particular, phase shift components B624a-B624b may be implemented as LC circuits and may include one or more passive components such as inductors and / or capacitors. These passive components may be connected in parallel and / or in series and may be connected between the output of amplifiers 314a-314b and the input of signal combiner B612, or the output of amplifiers 314a-314b and ground. You may connect between voltage. In some implementations, phase shift components B624a-B624b are integrated into the same die or into the same package as amplifiers 314a-314b.

  In some implementations (eg, as shown in FIG. 11), phase shift components B624a-B624b are provided after amplifiers 314a-314b along the path. That is, any signal attenuation caused by phase shift components B624a-B624b does not affect the performance of module B610, such as the signal-to-noise ratio of the output signal. However, in some implementations, phase shift components B624a-B624b are provided along the path before amplifiers 314a-314b. For example, the phase shift components B624a to B624b may be integrated into an impedance matching component provided between the diplexer B611 and the amplifiers 314a to 314b.

  FIG. 12 shows that in some embodiments, diversity receiver configuration B640 may include a DRx module B641 with one or more phase matching components B624a-B624b and two-stage amplifiers B614a-B614b. The DRx module B641 of FIG. 12 is similar to the DRx module B610 of FIG. 11 except that the amplifiers 314a to 314b of the DRx module B610 of FIG. 11 are replaced by the two-stage amplifiers B614a to B614b of the DRx module B641 of FIG. Substantially similar.

Substantially similar to module B610. The coupler post-stage amplifier B615 may be a variable gain amplifier (VGA) and / or a variable current amplifier controlled by a DRx controller (not shown), similar to the amplifiers 314a to 314b.

  FIG. 14 illustrates that, in some embodiments, diversity receiver configuration B700 can include a DRx module B710 with tunable phase shift components B724a-B724d. Each of the tunable phase shift components B724a-B724d can be configured to phase shift the signal passing through the tunable phase shift component by an amount controlled by the phase shift tuning signal received from the DRx controller B702.

  Diversity receiver configuration B 700 includes DRx module B 710 having an input coupled to antenna 140 and an output coupled to transmission line 135. The DRx module B 710 includes a certain number of paths between the inputs and outputs of the DRx module B 710. In some implementations, the DRx module B 710 includes one or more bypass paths (not shown) between the input and output that are activated by one or more bypass switches controlled by the DRx controller B 702.

  The DRx module B 710 includes a fixed number of multiplexer paths including an input multiplexer B 311 and an output multiplexer B 312. The multiplexer path includes a fixed number of on-module paths (shown). This includes an input multiplexer B311, bandpass filters B313a-B313d, amplifiers B314a-B314d, tunable phase shift components B724a-B724d, an output multiplexer B312 and a coupler post-amplifier B615. The multiplexer path may include one or more off-module paths (not shown) described herein. As also described herein, amplifiers B314a-B314d (including post-gain amplifier B615) may be variable gain amplifiers and / or variable current amplifiers.

  Tunable phase shift components B724a-B724d may include one or more variable components such as inductors and capacitors. These variable components may be connected in parallel and / or in series and may be connected between the output of amplifiers B314a-B314d and the input of output multiplexer B312 or the output of amplifiers B314a-B314d and the ground voltage. You may connect between.

  The DRx controller B 702 is configured to selectively activate one or more of the plurality of paths between the input and output. In some implementations, DRx controller B 702 is configured to selectively activate one or more of the plurality of paths based on a band selection signal received by DRx controller B 702 (eg, from a communication controller). Is done. DRx controller B702 may selectively activate the path, for example, by enabling or disabling amplifiers B314a-B314d, by controlling multiplexers B311, B312 or through other mechanisms described herein. it can.

  In some implementations, the DRx controller B702 is configured to tune the tunable phase shift components B724a-B724d. In some implementations, the DRx controller B702 tunes the tunable phase shift components B724a-B724d based on the band select signal. For example, the DRx controller B702 tunes the tunable phase shift components B724a-B724d based on a look-up table that associates multiple frequency bands (or multiple sets of frequency bands) indicated by a band selection signal with tuning parameters. Can do. Accordingly, the DRx controller B702 tunes the tunable phase shift component (or its variable component) in response to the band selection signal to the tunable phase shift of each active path in response to the band select signal. It can be transmitted to the parts B 724a to B 724d.

  DRx controller B702 can be tuned with tunable phase shift components B724a-B724d so that the out-of-band reflected signal is in phase with the out-of-band initial signal at output multiplexer B312. For example, a first path corresponding to the first frequency band (through the first amplifier B 314a), a second path corresponding to the second frequency band (through the second amplifier B 314b), and (through the third amplifier B 314c). When the band selection signal indicates that the third path is activated, the DRx controller B 702 (1) for the signal propagating along the second path (in the second frequency band), the initial signal And (2) along the third path so that the reflected signal that propagates backward along the first path, is reflected from the bandpass filter B313a, and is reflected in the forward direction through the first path is in phase. For signals that propagate (in the third frequency band), the initial signal and the reflected signal that propagates backward along the first path, is reflected from the bandpass filter B 313a, and propagates forward through the first path. And will be in phase A first tunable phase shifting parts B724a can be tuned to.

  The DRx controller B702 can tune the first tunable phase shift component B724a so that the second frequency band is phase shifted by an amount different from the third frequency band. For example, the signal in the second frequency band is phase-shifted by 140 degrees due to the backward propagation through the first amplifier B 314a, the reflection from the band pass filter B 313a, and the forward propagation through the first amplifier B 314b. When the frequency band is phase shifted by 130 degrees, the DRx controller B702 shifts the second frequency band by -70 degrees (or 110 degrees) and the third frequency band by -65 degrees (or 115 degrees). The first tunable phase shift component B 724a can be tuned so that it is phase shifted by a).

  Similarly, the DRx controller B702 can tune the second phase shift component B724b and the third phase shift component B724c.

  In another example, when the band select signal indicates that the first path, the second path, and the fourth path (through the fourth amplifier B 314d) are activated, the DRx controller B702 may: For a signal propagating along two paths (in the second frequency band), it propagates backward along the initial signal and the first path, is reflected from the bandpass filter B313a, and passes through the first path. (2) For signals propagating along the fourth path (in the fourth frequency band), the initial signal and counterpropagating along the first path so that the direction-propagating reflected signal is in phase. Then, the first tunable phase shift component B 724a can be tuned so that the reflected signal reflected from the band pass filter B 313a and propagating forward through the first path is in phase.

  The DRx controller B702 can tune the variable components of the tunable phase shift components B724a-B724d to have different values for different sets of frequency bands.

  In some implementations, the tunable phase shift components B724a-B724d are replaced by fixed phase shift components that are not tunable or not controlled by the DRx controller B702. Each one of the phase shift components provided along the corresponding one of the corresponding paths corresponding to one frequency band is shifted in the initial direction along the corresponding other path by phase-shifting each of the other frequency bands. The signal and the reflected signal that propagates backward along the one of the paths, is reflected from the corresponding bandpass filter, and propagates forward through the one of the paths are configured in phase. Good.

  For example, the third phase shift component B 724c is fixed, (1) an initial signal of the first frequency (propagating along the first path), and propagating backward along the third path, and passing through the third band. Phase shift of the first frequency band so that the reflected signal reflected from the filter B313c and forwardly propagated through the third path is in phase, (2) the second frequency (propagating along the second path) The second frequency band is set so that the initial signal of the first signal and the reflected signal propagating backward along the third path, reflected from the third bandpass filter B313c, and propagating forward through the third path are in phase. Phase-shifted, (3) propagated along the fourth path with the initial signal at the fourth frequency (propagating along the fourth path) and reflected back along the third path, reflected from the third bandpass filter B313c, Reflected signal propagating forward through Constituted a fourth frequency band to the phase shift so that phase. Other phase shift components may be similarly fixed and set.

  That is, the DRx module B 710 includes a DRx controller B 702 configured to selectively activate one or more of the plurality of paths between the input of the DRx module B 710 and the output of the DRx module B 710. The DRx module B710 further includes a plurality of amplifiers B314a to B314d. Each one of the plurality of amplifiers B314a to B314d is provided along a corresponding one of the plurality of paths, and is configured to amplify a signal received by the amplifier.

Each one of the plurality of phase shift components B724a to B724d is provided along a corresponding one of the plurality of paths, and is configured to phase shift a signal passing through the phase shift component.

  In some implementations, the first phase shift component B724a is provided along a first path corresponding to a first frequency band (eg, the frequency band of the first bandpass filter B313a) and passes through the first phase shift component B724a. An initial signal propagating along the second path corresponding to the second frequency band by shifting the phase of the second frequency band of the signal to be transmitted (for example, the frequency band of the second bandpass filter B313b), and along the first path The reflected signal propagating in this way is configured to be at least partially in phase.

  In some implementations, the first phase shift component B 724a can further phase shift a third frequency band of a signal that passes through the first phase shift component B 724a (eg, the frequency band of the third band pass filter B 313c). The initial signal propagating along the third path corresponding to the three frequency bands and the reflected signal propagating along the first path are configured to be at least partially in phase.

  Similarly, in some implementations, the second phase shift component B 724b provided along the second path causes the first frequency band of the signal passing through the second phase shift component B 724b to shift the first The initial signal propagating along the path and the reflected signal propagating along the second path are configured to be at least partially in phase.

The DRx module BC1010 may include one or more tunable impedance matching components provided at one or more of the inputs and outputs of the DRx module BC1010. In particular, the DRx module BC1010 may include an input tunable impedance matching component BC1016 provided at the input of the DRx module BC1010, an output tunable impedance matching component BC1017 provided at the output of the DRx module BC1010, or both.

  It is unlikely that all of the multiple frequency bands received at the same diversity antenna 140 are ideal impedance matching.

For example, the DRx controller BC 1002 may tune the tunable input impedance matching component BC 1016 based on a look-up table that associates multiple frequency bands (or multiple sets of frequency bands) indicated by a band selection signal with tuning parameters. it can. Accordingly, the DRx controller BC 1002 sends the input impedance tuning signal to the tunable input impedance matching component BC 1016 in response to the band selection signal to tune the tunable input impedance matching component (or its variable component) according to the tuning parameter. Can be sent.

  The tunable input impedance matching component BC1016 may be a tunable T-type circuit, a tunable π-type circuit, or any other tunable matching circuit.

You may connect between.

  Similarly, with only one transmission line 135 (or at least some transmission lines) carrying signals in many frequency bands, it is unlikely that all multiple frequency bands will be an ideal impedance match. A tunable output impedance matching component BC1017 is implemented at the output of the DRx module BC1010 to match each frequency band using a compact matching circuit (eg, based on a band select signal from a communication controller) DRx controller BC1002 Can be controlled by. For example, the DRx controller BC 1002 may tune the tunable output impedance matching component BC 1017 based on a look-up table that associates multiple frequency bands (or multiple sets of frequency bands) indicated by a band selection signal with tuning parameters. it can. Accordingly, in order to tune the tunable output impedance matching component (or its variable component) according to the tuning parameter, the DRx controller BC 1002 can tune the output impedance tuning signal to the tunable output impedance matching component BC 1017 in response to the band selection signal.

You may connect between.

  FIG. 18 illustrates that, in some embodiments, the diversity receiver configuration BC 1100 can include a DRx module BC 1110 with multiple tunable components.

In some implementations, the DRx module BC1110 includes one or more bypass paths (not shown) between the input and the output activated by one or more bypass switches controlled by the DRx controller BC1102.

  The DRx module BC1110 includes a fixed number of multiplexer paths including an input multiplexer BC311 and an output multiplexer BC312. The multiplexer path includes a fixed number of on-module paths (shown). This includes a tunable input impedance matching component BC1016, an input multiplexer BC311, bandpass filters BC313a-BC313d, tunable impedance matching components BC934a-BC934d, amplifiers BC314a-BC314d, tunable phase shift components BC724a-BC724d, an output multiplexer BC312, and A tunable output impedance matching component BC1017 is included. The multiplexer path may include one or more off-module paths (not shown) described herein. Again, as described herein, amplifiers BC 314a-BC 314d may be variable gain amplifiers and / or variable current amplifiers.

In some implementations, the DRx controller BC 1102 is configured to transmit amplifier control signals to one or more amplifiers BC 314a-BC 314d, each provided along one or more activated paths. The amplifier control signal controls the gain (or current) of the amplifier serving as the transmission destination.

For example, the DRx controller BC 1102 can tune a tunable component based on a look-up table that associates multiple frequency bands (or multiple sets of frequency bands) indicated by a band selection signal with tuning parameters. Therefore, the DRx controller BC 1101 transmits a tuning signal to the tunable component (active path) in response to the band selection signal to tune the tunable component (or its variable component) according to the tuning parameter. Can do. In some implementations, the DRx controller BC 1102 tunes the tunable component based at least in part on the amplifier control signal to control the gain and / or current of the amplifiers BC 314a-BC 314d. In various implementations, one or more of the tunable components may be replaced by fixed components that are not controlled by the DRx controller BC1102.

  Note that one tuning of a tunable part can affect the tuning of other tunable parts. That is, the tuning parameter in the lookup table for the first tunable part may be based on the tuning parameter for the second tunable part. For example, the tuning parameters for tunable phase shift components BC724a-BC724d may be based on the tuning parameters for tunable impedance matching components BC934a-BC934d. In other examples, the tuning parameters for the tunable impedance matching components BC934a-BC934d may be based on the tuning parameters for the tunable input impedance matching component BC1016.

  The controller can tune the tunable component based on a look-up table that associates multiple frequency bands (or sets of frequency bands) indicated by the band selection signal with tuning parameters. Thus, the DRx controller sends a tuning signal to the tunable component (in the active path) in response to the band select signal to tune the tunable component (or its variable component) in response to the tuning parameter. Can do. In some implementations, the controller is based at least in part on the amplifier control signal to control the gain and / or current of one or more amplifiers, each provided along one or more activated paths. Tune the tunable parts.

  Example C: Impedance shift component

  FIG. 15 illustrates that, in some embodiments, diversity receiver configuration C800 can include a DRx module C810 with one or more impedance matching components C834a-C834b. The DRx module C810 includes two paths from the input of the DRx module C810 coupled to the antenna 140 to the output of the DRx module C810 coupled to the transmission line 135.

  In the DRx module C810 of FIG. 15 (as in the DRx module B610 of FIG. 11), the signal divider and bandpass filter are implemented as a diplexer C611. Diplexer C611 includes an input coupled to the antenna, a first output coupled to first impedance matching component C834a, and a second output coupled to second impedance matching component C834b. At the first output, the diplexer C611 outputs the signal received at the input filtered into the first frequency band (eg, from the antenna 140). At the second output, the diplexer C611 outputs the signal received at the input filtered to the second frequency band.

  The impedance matching components C834a to C634d are provided between the diplexer C611 and the amplifiers C314a to C314b, respectively. As described herein, each one of amplifiers C314a-C314b is provided along a corresponding one of the paths and is configured to amplify the signal received at the amplifier. The outputs of the amplifiers C314a to C314b are supplied to the signal combiner C612.

  The signal combiner C612 includes a first input coupled to the first amplifier C314a, a second input coupled to the second amplifier C314b, and an output coupled to the output of the DRx module C610. The signal at the output of the signal combiner is the sum of the signals at the first and second inputs.

  When a signal is received by the antenna 140, the signal is filtered by the diplexer C611 to the first frequency band and propagates along a first path through the first amplifier C314a. Similarly, the signal is filtered by the diplexer C611 to the second frequency band and propagates along a second path through the second amplifier C314b.

  Each path can be characterized by noise figure and gain. The noise figure of each path represents the signal to noise ratio (SNR) degradation caused by the amplifiers and impedance matching components provided along that path. In particular, the noise figure of each path is the decibel (dB) difference between the SNR at the input of the impedance matching components C834a-C834b and the SNR at the output of the amplifiers C314a-C314b. That is, the noise figure is a measure of the difference between the noise output of an amplifier with the same gain and the noise output of an “ideal” amplifier (no noise is generated). Similarly, the gain for each path represents the gain provided by the amplifiers and impedance matching components provided along that path.

  The noise figure and gain of each path can be different for different frequency bands. For example, the first path may have an in-band noise figure and in-band gain for the first frequency band and an out-of-band noise figure and out-of-band gain for the second frequency band. Similarly, the second path may have an in-band noise figure and in-band gain for the second frequency band and an out-of-band noise figure and out-of-band gain for the first frequency band.

  The DRx module C810 can also be characterized by a noise figure and gain that can be different for different frequency bands. In particular, the noise figure of DRx module C810 is the dB difference between the SNR at the input of DRx module C810 and the SNR at the output of DRx module C810.

  The noise figure and gain of each path (in each frequency band) may depend, at least in part, on the impedance (in each frequency band) of the impedance matching components C834a-C834b. Thus, the impedance of the impedance matching components C834a-C834b may be advantageous to minimize the in-band noise figure of each path and / or maximize the in-band gain of each path. That is, in some implementations, impedance matching components C834a-C834b each reduce the in-band noise figure of its corresponding path and / or its response (compared to a DRx module lacking such impedance matching components C834a-C834b). It is configured to increase the in-band gain of the path.

  Because signals propagating along the two paths are combined by signal combiner C612, out-of-band noise generated or amplified by the amplifier can negatively affect the combined signal. For example, out-of-band noise generated or amplified by the first amplifier C 314a may increase the noise figure of the DRx module C 810 at the second frequency. Accordingly, the impedance of impedance matching components C834a-C834b may be advantageous to minimize the out-of-band noise figure of each path and / or minimize the out-of-band gain of each path. That is, in some implementations, impedance matching components C834a-C834b each reduce the out-of-band noise figure of its corresponding path and / or its response (compared to a DRx module lacking such impedance matching components C834a-C834b). It is configured to reduce the out-of-band gain of the path.

  The impedance matching components C834a to C834b may be mounted as a passive circuit. In particular, impedance matching components C834a-C834b may be implemented as RLC circuits and may include one or more passive components such as resistors, inductors and / or capacitors. The passive components may be connected in parallel and / or in series and may be connected between the output of the diplexer C611 and the inputs of the amplifiers C314a to C314b, or connected between the output of the diplexer C611 and the ground voltage. You can do it. In some implementations, impedance matching components C834a-C834b are integrated on the same die or in the same package as amplifiers C314a-C314b.

  As described herein, for a particular path, the impedance of impedance matching components C834a-C834b minimizes in-band noise figure, maximizes in-band gain, minimizes out-of-band noise figure, and out-of-band gain. It can be advantageous to minimize. To achieve all four goals, with only two degrees of freedom (eg impedance in the first frequency band and impedance in the second frequency band) or various other constraints (eg number of parts, cost, die space ) To design the impedance matching components C834a to C834b is a difficult task. Thus, in some implementations, the in-band metric of the in-band noise figure minus the in-band gain is minimized, and the out-of-band metric of the out-of-band noise figure plus the out-of-band gain is minimized. . Designing impedance matching components C834a-C834b to achieve both of these goals with various constraints can still be a challenge. That is, in some implementations, the in-band metric is minimized under a set of constraints, and the out-of-band metric is the set of constraints and the in-band metric is a threshold amount (eg, 0.1 dB, 0.2 dB). , 0.5 dB, or any other value) and is minimized subject to additional constraints. Therefore, the impedance matching component can use an in-band metric minimum threshold value, such as an in-band metric minimum value that can be obtained under any constraints, for example, the in-band noise figure minus the in-band gain. Configured to reduce to within quantity. The impedance matching component further ensures that the out-of-band metric, which is the out-of-band noise figure plus the out-of-band gain, does not increase the in-band constrained out-of-band minimum, for example, the in-band metric beyond the threshold. It is configured to reduce to the smallest possible out-of-band metric subject to additional constraints. In some implementations, the composite metric of the in-band metric (weighted by the in-band factor) plus the out-of-band metric (weighted by the out-of-band factor) is minimized subject to arbitrary constraints .

  That is, in some implementations, impedance matching components C834a-C834b each reduce the in-band metric (in-band noise figure minus in-band gain) of the corresponding path (eg, reduce in-band noise figure). Configured to decrease (by increasing the in-band gain, or both). In some implementations, each of the impedance matching components C834a-C834b further reduces the out-of-band metric (out-of-band noise figure plus out-of-band gain) of its corresponding path (eg, reduces the out-of-band noise figure). Configured to decrease the out-of-band gain, or both).

  In some implementations, by reducing the out-of-band metric, the impedance matching components C834a-C834b allow the DRx module C810 to increase in one or more of the frequency bands without substantially increasing the noise figure in other frequency bands. Reduce the noise figure.

  FIG. 16 illustrates that in some embodiments, the diversity receiver configuration C900 can include a DRx module C910 with tunable impedance matching components C934a-C934d. Each of the tunable impedance matching components C934a-C934d can be configured to present an impedance controlled by an impedance tuning signal received from the DRx controller C902.

  Diversity receiver configuration C900 includes a DRx module C910 having an input coupled to antenna 140 and an output coupled to transmission line 135. The DRx module C910 includes a certain number of paths between the inputs and outputs of the DRx module C910. In some implementations, the DRx module C910 includes one or more bypass paths (not shown) between inputs and outputs that are activated by one or more bypass switches controlled by the DRx controller C902.

  The DRx module C910 includes a fixed number of multiplexer paths including an input multiplexer C311 and an output multiplexer 312. The multiplexer path includes a fixed number of on-module paths (shown) including an input multiplexer C311, bandpass filters C313a-C313d, tunable impedance matching components C934a-C934d, amplifiers C314a-C314d and an output multiplexer C312. The multiplexer path may include one or more off-module paths (not shown) described herein. Again, as described herein, amplifiers C314a-C314d may be variable gain amplifiers and / or variable current amplifiers.

  The tunable impedance matching components C934a-C934b can be tunable T-type circuits, tunable π-type circuits, or any other tunable matching circuit. Tunable impedance matching components C934a-C934d may include one or more variable components such as resistors, inductors and capacitors. These variable components may be connected in parallel and / or in series and may be connected between the output of the input multiplexer C311 and the inputs of the amplifiers C314a to C314d, or the output of the input multiplexer C311 and the ground voltage. You may connect between.

  The DRx controller C902 is configured to selectively activate one or more of the plurality of paths between the input and output. In some implementations, the DRx controller C902 is configured to selectively activate one or more of the plurality of paths based on a band selection signal received by the DRx controller C902 (eg, from a communication controller). . DRx controller C902 may selectively activate the path, for example, by enabling or disabling amplifiers C314a-C314d, by controlling multiplexers C311, C312 or through other mechanisms described herein. it can.

  In some implementations, the DRx controller C902 is configured to tune the tunable impedance matching components C934a-C934d. In some implementations, the DRx controller C702 tunes the tunable impedance matching components C934a-C934d based on the band select signal. For example, the DRx controller C902 tunes the tunable impedance matching components C934a-C934d based on a look-up table that associates multiple frequency bands (or multiple sets of frequency bands) indicated by a band selection signal with tuning parameters. Can do. Accordingly, in order to tune the tunable impedance matching component (or its variable component) in response to the tuning parameter, the DRx controller C 902 responds to the band selection signal by sending the impedance tuning signal to the tunable impedance of each active path. It can be transmitted to the matching parts C934a to C934d.

  In some implementations, the DRx controller C902 tunes the tunable impedance matching components C934a-C934d based at least in part on the amplifier control signal transmitted to control the gain and / or current of the amplifiers C314a-C314d. To do.

  In some implementations, DRx controller C902 tunes each active path tunable impedance matching component C934a-C934d to minimize (or reduce) in-band noise figure and maximize in-band gain. (Or increased) so that the out-of-band noise figure for each of the other active paths is minimized (or reduced) and / or the out-of-band gain for each of the other active paths is minimized (or reduced). Composed.

  In some implementations, the DRx controller C902 tunes each active path tunable impedance matching component C934a-C934d for each of the other active paths (from the inband noise figure). The in-band gain minus) is minimized (or reduced), and the out-of-band metric (out-of-band noise figure plus out-of-band gain) is minimized (or reduced).

  In some implementations, the DRx controller C902 can minimize (or reduce) the in-band metric subject to a set of constraints by tuning the tunable impedance matching components C934a-C934d of each active path, The out-of-band metric for each of the other active paths increases with the set of constraints and the in-band metric exceeds the threshold (eg, 0.1 dB, 0.2 dB, 0.5 dB, or any other value) It is minimized (or reduced) subject to the additional constraint of not doing so.

  That is, in some implementations, the DRx controller C902 tunes each active path tunable impedance matching component C934a-C934d so that the tunable impedance matching component derives the inband gain from the inband noise figure. An in-band metric that is negative is configured to be reduced to within an in-band metric minimum, eg, a threshold amount of possible in-band metric minimum under any constraints. The DRx controller C902 further tunes each active path tunable impedance matching component C934a-C934d so that the tunable impedance matching component is an out-of-band noise figure plus an out-of-band gain. Reduce metrics to the smallest possible out-of-band metric, such as in-band constrained out-of-band minimums, for example, with additional constraints to prevent the in-band metric from increasing beyond the threshold Configured as follows.

  In some implementations, the DRx controller C902 tunes each active path tunable impedance matching component C934a-C934d to an inband metric (weighted by the inband factor) (other active Configured so that composite metrics, plus the out-of-band metrics for other active paths (weighted by out-of-band factors for each path), are minimized (or reduced) subject to arbitrary constraints Is done.

  The DRx controller C902 can tune the variable components of the tunable impedance matching components C934a-C934d to have different values for different sets of frequency bands.

  In some implementations, the tunable impedance matching components C934a-C934d may be replaced by fixed impedance matching components that are not tunable and cannot be controlled by the DRx controller C902. Each one of the impedance matching components provided along a corresponding one of the paths corresponding to one frequency band is configured to reduce (or minimize) the in-band metric for that one frequency band And may be configured to reduce (or minimize) out-of-band metrics for one or more of the other frequency bands (eg, each of the other frequency bands).

  For example, the third impedance matching component C934c is fixed and (1) reduces the in-band metric for the third frequency band, (2) reduces the out-of-band metric for the first frequency band, (3) configured to reduce an out-of-band metric for the second frequency band and / or (4) to reduce an out-of-band metric for the fourth frequency band. Other impedance matching components may be similarly fixed and configured.

  That is, the DRx module C910 includes a DRx controller C902 configured to selectively select a plurality of paths between the input of the DRx module C910 and the output of the DRx module C910. The DRx module C910 further includes a plurality of amplifiers C314a to C314d. Each one of the plurality of amplifiers C314a to C314d is provided along a corresponding one of the plurality of paths, and is configured to amplify a signal received by the amplifier.

  In some implementations, the first impedance matching component C934a further includes at least an out-of-band noise figure or an out-of-band gain for a third frequency band (eg, the frequency band of the third bandpass filter C313c) corresponding to the third path. Configured to reduce one.

  Similarly, in some implementations, the second impedance matching component C934b provided along the second path is configured to reduce at least one of the out-of-band noise figure or the out-of-band gain for the first frequency band. Composed.

  FIG. 17 illustrates that in some embodiments, the diversity receiver configuration BC1000 can include a DRx module BC1010 with tunable impedance matching components provided at the input and output. The DRx module BC1010 may include one or more tunable impedance matching components provided at one or more of the inputs and outputs of the DRx module BC1010. In particular, the DRx module BC1010 may include an input tunable impedance matching component BC1016 provided at the input of the DRx module BC1010, an output tunable impedance matching component BC1017 provided at the output of the DRx module BC1010, or both.

  It is unlikely that all of the multiple frequency bands received at the same diversity antenna 140 are ideal impedance matching. A tunable input impedance matching component BC1016 is implemented at the input of the DRx module BC1010 (eg, based on a band select signal from a communication controller) to match each frequency band using a compact matching circuit.

A tunable output impedance matching component BC1017 is implemented at the output of the DRx module BC1010 to match each frequency band using a compact matching circuit (eg, based on a band select signal from a communication controller) DRx controller BC1002 Can be controlled by. For example, the DRx controller BC 1002 may tune the tunable output impedance matching component BC 1017 based on a look-up table that associates multiple frequency bands (or multiple sets of frequency bands) indicated by a band selection signal with tuning parameters. it can.

  FIG. 18 illustrates that, in some embodiments, the diversity receiver configuration BC 1100 can include a DRx module BC 1110 with multiple tunable components. Diversity receiver configuration BC 1100 includes a DRx module BC 1110 having an input coupled to antenna 140 and an output coupled to transmission line 135. The DRx module BC1110 includes a certain number of paths between the inputs and outputs of the DRx module BC1110. In some implementations, the DRx module BC1110 includes one or more bypass paths (not shown) between the input and the output activated by one or more bypass switches controlled by the DRx controller BC1102.

  The DRx module BC1110 includes a fixed number of multiplexer paths including an input multiplexer BC311 and an output multiplexer BC312. The multiplexer path includes a fixed number of on-module paths (shown). This includes a tunable input impedance matching component BC1016, an input multiplexer BC311, bandpass filters BC313a-BC313d, tunable impedance matching components BC934a-BC934d, amplifiers BC314a-BC314d, tunable phase shift components BC724a-BC724d, an output multiplexer BC312, and A tunable output impedance matching component BC1017 is included.

DRx controller BC902 may selectively activate the path, for example, by enabling or disabling amplifiers BC314a-BC314d, by controlling multiplexers BC311, BC312 or via other mechanisms described herein. it can. In some implementations, the DRx controller BC 1102 is configured to transmit amplifier control signals to one or more amplifiers BC 314a-BC 314d, each provided along one or more activated paths. The amplifier control signal is the. Control gain (or current).

  DRx controller BC1102 is configured to tune one or more of tunable input impedance matching component BC1016, tunable impedance matching components BC934a-BC934d, tunable phase shift components BC724a-BC724d, and tunable output impedance matching component BC1017. . For example, the DRx controller BC 1102 can tune a tunable component based on a look-up table that associates multiple frequency bands (or multiple sets of frequency bands) indicated by a band selection signal with tuning parameters. Therefore, the DRx controller BC 1101 transmits a tuning signal to the tunable component (active path) in response to the band selection signal to tune the tunable component (or its variable component) according to the tuning parameter. Can do. In some implementations, the DRx controller BC 1102 tunes the tunable component based at least in part on the amplifier control signal to control the gain and / or current of the amplifiers BC 314a-BC 314d. In various implementations, one or more of the tunable components may be replaced by fixed components that are not controlled by the DRx controller BC1102.

  Note that one tuning of a tunable part can affect the tuning of other tunable parts. That is, the tuning parameter in the lookup table for the first tunable part may be based on the tuning parameter for the second tunable part. For example, the tuning parameters for tunable phase shift components BC724a-BC724d may be based on the tuning parameters for tunable impedance matching components BC934a-BC934d. In other examples, the tuning parameters for the tunable impedance matching components BC934a-BC934d may be based on the tuning parameters for the tunable input impedance matching component BC1016.

  FIG. 19 illustrates one embodiment of a flowchart representation of a method for processing an RF signal. In some implementations (and as detailed below by way of example), method BC 1200 is performed by a controller such as DRx controller BC 1102 of FIG. In some implementations, the method BC 1200 is performed by processing logic that includes hardware, firmware, software, or a combination thereof. In some implementations, the method BC 1200 is performed by a processor that executes code stored on a non-transitory computer readable medium (eg, memory). Briefly, method BC 1200 includes receiving a band selection signal and routing the received RF signal to one or more tuned paths to process the received RF signal.

  Method BC1200 begins at block BC1210, where the controller receives a band select signal. The controller can receive a band selection signal from another controller or a band selection signal from a cellular base station or other external source. The band selection signal can indicate one or more frequency bands in which the wireless device transmits and receives RF signals. In some implementations, the band selection signal indicates a set of frequency bands for carrier aggregation communication.

  In block BC1220, the controller selectively activates one or more paths of the diversity receiver (DRx) module based on the band selection signal. As described herein, a DRx module is between one or more inputs (coupled to one or more antennas) and one or more outputs (coupled to one or more transmission lines) of the DRx module. A certain number of paths may be included. The path may include a bypass path and a multiplexer path. The multiplexer path can include an on-module path and an off-module path.

  The controller may divide one or more of the plurality of paths by, for example, enabling or disabling an amplifier provided along the path by opening or closing one or more bypass switches via an amplifier enable signal. It can be selectively activated by control of one or more multiplexers via control signals and / or coupler control signals, or through other mechanisms. For example, the controller can open or close a switch provided along the path, or set the gain of an amplifier provided along the path to substantially zero.

  At block BC1230, the controller sends a tuning signal to one or more tunable components provided along one or more activated paths. Tunable components include a tunable impedance matching component provided at the input of the DRx module, a plurality of tunable impedance matching components provided along a plurality of paths, and a plurality along the plurality of paths, respectively. One or more of a plurality of tunable phase shift components provided and a tunable output impedance matching component provided at the output of the DRx module.

  The controller can tune the tunable component based on a look-up table that associates multiple frequency bands (or sets of frequency bands) indicated by the band selection signal with tuning parameters. Thus, the DRx controller sends a tuning signal to the tunable component (in the active path) in response to the band select signal to tune the tunable component (or its variable component) in response to the tuning parameter. Can do. In some implementations, the controller is based at least in part on the amplifier control signal to control the gain and / or current of one or more amplifiers, each provided along one or more activated paths. Tune the tunable parts.

  In particular, the above-described example C relating to the impedance shift component can be summarized as follows.

  Example D: Amplifier post filter

  FIG. 20 illustrates that in some embodiments, the diversity receiver configuration D400 includes a diversity receiver (DRx) module D410 having a plurality of bandpass filters D423a-D423d provided at the outputs of the plurality of amplifiers D314a-D314d. Show you get. Diversity receiver configuration D400 includes a DRx module D410 having an input coupled to antenna 140 and an output coupled to transmission line 135. The DRx module D410 includes a certain number of paths between the inputs and outputs of the DRx module D410. Each path includes an input multiplexer D311, amplifier pre-stage bandpass filters D413a to D413d, amplifiers D314a to D314d, amplifier post-stage bandpass filters D423a to D423d, and an output multiplexer D312.

  The DRx controller D302 is configured to selectively activate one or more of the plurality of paths between the input and output. In some implementations, the DRx controller D302 is configured to selectively activate one or more of the plurality of paths based on a band selection signal received by the DRx controller D302 (eg, from a communication controller). . The DRx controller D302 can selectively activate the path, for example, by enabling or disabling the amplifiers D314a to D314d, controlling the multiplexers D311 and D312 or via other mechanisms.

  The output of the DRx module D410 is passed through the transmission line 135 to the diversity RF module D420. Diversity RF module D420 differs from diversity RF module 320 of FIG. 3 in that diversity RF module D420 of FIG. 20 does not include a downstream bandpass filter. In some implementations (eg, as shown in FIG. 20), the downstream multiplexer D321 may be implemented as a sample switch.

  Inclusion of amplifier back bandpass filters D423a-D423d in DRx module D410 instead of diversity RF module D420 may provide a certain number of advantages. For example, as detailed below, such a configuration improves the noise figure of DRx module D410, simplifies filter design, and / or improves path isolation.

  Each path of the DRx module D410 can be characterized by a noise figure. The noise figure for each path represents the signal to noise ratio (SNR) degradation caused by propagation along the path. In particular, the noise figure of each path can be expressed as a decibel (dB) difference between the SNR at the input of the amplifier pre-stage bandpass filters D413a to D413d and the SNR at the output of the amplifier post-stage bandpass filters D423a to D4234b. The noise figure of each path can be different for different frequency bands. For example, the first path may have an in-band noise figure for the first frequency band and an out-of-band noise figure for the second frequency band. Similarly, the second path may have an in-band noise figure for the second frequency band and an out-of-band noise figure for the first frequency band.

  The DRx module D410 can also be characterized by a noise figure that can be different for different frequency bands. In particular, the noise figure of DRx module D410 is the dB difference between the SNR at the input of DRx module D410 and the SNR at the output of DRx module D410.

  Since signals propagating along the two paths are combined by output multiplexer D312, out-of-band noise generated or amplified by the amplifier can negatively affect the combined signal. For example, out-of-band noise generated or amplified by the first amplifier D 314a may increase the noise figure of the DRx module D410 at the second frequency. That is, the amplifier post-stage bandpass filter D423a provided along the path can reduce this out-of-band noise and reduce the noise figure of the DRx module D410 at the second frequency.

  In some implementations, the amplifier pre-band pass filters D413a-D413d and the amplifier post-band pass filters D423a-D423d can be designed to be complementary, thus simplifying the filter design with lower cost and fewer components and / or Similar performance is achieved. For example, the amplifier post-stage bandpass filter D423a provided along the first path can strongly attenuate the frequency that is weakly attenuated by the amplifier pre-stage bandpass filter D413a provided along the first path. In one example, the amplifier pre-stage bandpass filter D413a can attenuate frequencies below the first frequency band rather than frequencies above the first frequency band. Complementarily, the amplifier post-stage bandpass filter D423a can attenuate the frequency above the first frequency band rather than the frequency below the first frequency band. That is, the amplifier pre-stage bandpass filter D413a and the amplifier post-stage bandpass filter D423a together use a small number of components to attenuate all out-of-band frequencies. In general, one of the bandpass filters provided along one path can attenuate a frequency lower than the corresponding frequency band of the path more than a frequency higher than the corresponding frequency band, and is provided along the path. Another one of the obtained bandpass filters can attenuate a frequency above the corresponding frequency band more than a frequency below the corresponding frequency band. The amplifier front-stage bandpass filters D413a to D413d and the amplifier rear-stage bandpass filters D423a to D423d can be complementary in another manner. For example, an amplifier pre-stage bandpass filter D413a provided along the first path can shift the phase of the signal by a certain frequency, and an amplifier post-stage bandpass filter D423a provided along the first path The signal can be phase-shifted in reverse by the frequency.

  In some implementations, amplifier post-band pass filters D423a-D423d can improve path isolation. For example, without an amplifier post-stage bandpass filter, the signal propagating along the first path can be filtered to the first frequency by the amplifier pre-stage bandpass filter D413a and amplified by the amplifier D314a. As a result of leakage through the output multiplexer D312, the signal propagates in the reverse direction along the second path, and is reflected from the amplifier D314b, the amplifier pre-stage bandpass filter D413b, or other components provided along the second path. Can be done. If this reflected signal is out of phase with the initial signal, the signal is weakened when combined by output multiplexer D312. In contrast, according to the amplifier post-band pass filter, the leakage signal (mainly in the first frequency band) is provided along the second path and associated with the second frequency band. Since it is attenuated by the filter D423b, the influence of an arbitrary reflected signal is reduced.

  That is, the DRx module D410 selectively activates one or more of the plurality of paths between the input of the first multiplexer (eg, the input multiplexer D311) and the output of the second multiplexer (eg, the output multiplexer D312). Includes a configured controller. The DRx module D410 further includes a plurality of amplifiers D314a to D314d. Each one of the plurality of amplifiers D314a to D314d is provided along a corresponding one of the plurality of paths, and is configured to amplify a signal received by the amplifier. The DRx module D410 includes a first plurality of bandpass filters (for example, amplifier rear-stage bandpass filters D423a to D423d). Each one of the first plurality of bandpass filters is provided along a corresponding one of the plurality of paths at one output corresponding to each of the plurality of amplifiers D314a to D314d, and receives a signal received by the bandpass filter. It is configured to filter into each frequency band. As shown in FIG. 20, in some implementations, the DRx module D410 further includes a second plurality of bandpass filters (eg, amplifier pre-stage bandpass filters D413a-D413d). Each one of the second plurality of bandpass filters is provided at the input of one of the corresponding amplifiers of the plurality of amplifiers D314a to D314d along the corresponding one of the plurality of paths, and the signal received by the bandpass filter Are configured to be filtered into each frequency band.

  FIG. 21 illustrates that in some embodiments, the diversity receiver configuration D450 may include a diversity RF module D460 with fewer amplifiers than the diversity receiver (DRx) module D410. As mentioned herein, in some implementations diversity RF module D460 may not include a bandpass filter. That is, in some implementations, one or more amplifiers D424 of diversity RF module D460 need not be band specific. In particular, the diversity RF module D460 may include one or more paths. Each path includes an amplifier D424 that is not mapped one-to-one to the path of the DRx module D410. The mapping of such paths (or corresponding amplifiers) can be stored in the controller 120.

  Thus, DRx module D410 includes a certain number of paths, each corresponding to one frequency band, while diversity RF module D460 does not support a single frequency band (from the input of diversity RF module D460 to the input of multiplexer D321). ) It may include one or more routes.

  In some implementations (shown in FIG. 21), diversity RF module D460 includes a single wideband or tunable amplifier D424 that amplifies the signal received from transmission line 135 and outputs the amplified signal to multiplexer D321. . Multiplexer D321 includes a plurality of multiplexer outputs, each corresponding to each frequency band. In some implementations, the multiplexer D321 may be implemented as a sample switch. In some implementations, diversity RF module D460 does not include any amplifier.

  In some implementations, the diversity signal is a single band signal. That is, in some implementations, the multiplexer D321 is a unipolar / multi-thrower that routes the diversity signal to one of multiple outputs corresponding to the frequency band of the single band signal based on the signal received from the controller 120. (SPMT) switch. In some implementations, the diversity signal is a multiband signal. That is, in some implementations, the multiplexer D421 converts the diversity signal based on the divider control signal received from the controller 120 into two or more corresponding to two or more frequency bands of multiple-band signals of multiple outputs. It is a band divider for routing. In some implementations, the diversity RF module D460 can be combined with the transceiver D330 into a single module.

  In some implementations, diversity RF module D460 includes multiple amplifiers, each corresponding to a set of frequency bands. The signal from the transmission line 135 can be supplied to a band divider that outputs high frequency to the high frequency amplifier along the first path and outputs low frequency to the low frequency amplifier along the second path. The output of each amplifier can be provided to a multiplexer D321 that is configured to route the signal to a corresponding input of a transceiver D330.

  FIG. 22 illustrates that in some embodiments, the diversity receiver configuration D500 can include a DRx module D510 coupled to one or more off-module filters D513, D523. The DRx module D510 may include a packaging substrate D501 configured to receive a plurality of components, and a receiving system mounted on the packaging substrate D501. The DRx module D510 may include one or more signal paths routed out of the DRx module D510 and made available to system integrators, designers, or manufacturers that support filters for any desired band.

  The DRx module D510 includes a certain number of paths between the inputs and outputs of the DRx module D510. The DRx module D510 includes a bypass path between input and output that is activated by a bypass switch D519 controlled by a DRx controller D502. Despite the fact that FIG. 22 illustrates a single bypass switch D519, in some implementations, the bypass switch D519 includes multiple switches (eg, a first switch located near the input physically and an output physical switch). Second switch provided near the target). As shown in FIG. 22, the bypass path does not include a filter or an amplifier.

  The DRx module D510 includes a certain number of multiplexer paths including a first multiplexer D511 and a second multiplexer D512. The multiplexer path includes a certain number of on-module paths. This includes a first multiplexer D511, pre-amplifier bandpass filters D413a to D413d mounted on the packaging substrate D501, amplifiers D314a to D314d mounted on the packaging substrate D501, and post-amplifier bandpass mounted on the packaging substrate D501. Filters D423a to D423d and a second multiplexer D512 are included. The multiplexer path includes one or more off-module paths. This includes a first multiplexer D511, an amplifier pre-stage bandpass filter D513 mounted on the packaging substrate D501, an amplifier D514, an amplifier post-stage bandpass filter D523 mounted on the packaging substrate D501, and a second multiplexer D512. The amplifier D514 can be a broadband amplifier mounted on the packaging substrate D501 or can be mounted outside the packaging substrate D501. In some implementations, the one or more off-module paths do not include the amplifier pre-stage bandpass filter D513, but include the amplifier post-stage bandpass filter D523. As described herein, amplifiers D314a-D314d, D514 may be variable gain amplifiers and / or variable current amplifiers.

  The DRx controller D502 is configured to selectively activate one or more of the plurality of paths between the input and the output. In some implementations, the DRx controller D502 is configured to selectively activate one or more of the plurality of paths based on a band selection signal received from the DRx controller D502 (eg, from a communication controller). The The DRx controller D502 selectively activates the path, for example, by opening or closing the bypass switch D519, enabling or disabling the amplifiers D314a to D314d and D514, controlling the multiplexers D511 and D512, or via other mechanisms. Can be. For example, DRx controller D502 opens or closes a switch along the path (eg, between filters D313a-D313d, D513 and amplifiers D314a-D314d, D514), or substantially increases the gain of amplifiers D314a-D314d, D514. Can be set to zero.

  FIG. 23 illustrates that in some embodiments, the diversity receiver configuration D600 can include a DRx module D610 with a tunable matching circuit. In particular, the DRx module D610 may include one or more tunable matching circuits provided at one or more of the inputs and outputs of the DRx module D610.

  All of the multiple frequency bands received at the same diversity antenna 140 are unlikely to be ideal impedance matching. To match each frequency band using a compact matching circuit, a tunable input matching circuit D616 is implemented at the input of the DRx module D610 (eg, based on a band selection signal from the communication controller) by the DRx controller D602. Can be controlled. The DRx controller D602 can tune the tunable input matching circuit D616 based on a lookup table that associates multiple frequency bands (or sets of frequency bands) with tuning parameters. Tunable input matching circuit D616 may be a tunable T-type circuit, a tunable π-type circuit, or any other tunable matching circuit. In particular, the tunable input matching circuit D616 may include one or more variable components such as resistors, inductors and capacitors. These variable components may be connected in parallel and / or in series and may be connected between the input of the DRx module D610 and the input of the first multiplexer D311 or the input of the DRx module D610 and the ground voltage. You may connect between.

  Similarly, with only one transmission line 135 (or at least some cables) carrying signals in many frequency bands, it is unlikely that all multiple frequency bands will be an ideal impedance match. To match each frequency band using a compact matching circuit, a tunable output matching circuit D617 is implemented at the output of the DRx module D610 (eg, based on a band selection signal from the communication controller) by the DRx controller D602. Can be controlled. The DRx controller D602 can tune the tunable output matching circuit D618 based on a lookup table that associates multiple frequency bands (or sets of frequency bands) with tuning parameters. The tunable output matching circuit D617 may be a tunable T-type circuit, a tunable π-type circuit, or any other tunable matching circuit. In particular, the tunable output matching circuit D617 may include one or more variable components such as resistors, inductors and capacitors. These variable components may be connected in parallel and / or in series and may be connected between the output of the DRx module D610 and the output of the second multiplexer D312 or the output of the DRx module D610 and the ground voltage. You may connect between.

  In particular, the aforementioned example D for the amplifier post-filter can be summarized as follows.

  Example E: Switching network

  FIG. 24 illustrates that in some embodiments, the diversity receiver configuration E500 can include a DRx module E510 with a single pole / single throw switch E519. The DRx module E510 includes two paths from the input of the DRx module E510 coupled to the antenna 140 to the output of the DRx module E510 coupled to the transmission line 135. The DRx module E510 includes a plurality of amplifiers E514a to E514b. Each one of the plurality of amplifiers E514a to E514b is provided along a corresponding one of the plurality of paths, and is configured to amplify a signal received by the amplifier. In some implementations, as shown in FIG. 24, at least one of the plurality of amplifiers includes a two-stage amplifier.

  In the DRx module E510 of FIG. 24, the signal divider and the band pass filter are implemented as a diplexer E511. The diplexer E511 includes an input coupled to the antenna 140, a first output coupled to the phase shift component E527a provided along the first path, and a second phase shift component E527b disposed along the second path. And a second output coupled to. At the first output, the diplexer E511 outputs a signal received at the input (eg, from the antenna 140) and filtered to the first frequency band. At the second output, the diplexer E511 outputs a signal received at the input and filtered to the second frequency band. In some implementations, the diplexer E511 is configured to split the input signal received at the input of the DRx module E510 into a plurality of signals in each of a plurality of frequency bands that are propagated along a plurality of paths. A triplexer, quadplexer, or any other multiplexer may be substituted.

  In some implementations, an output multiplexer or other signal combiner provided at the output of the DRx module, such as the second multiplexer 312 of FIG. 3, degrades the performance of the DRx module when receiving a single band signal. Can be. For example, the output multiplexer may attenuate noise or introduce it into a single band signal. In some implementations, when multiple amplifiers, such as amplifiers 314a-314d of FIG. 3, are simultaneously enabled to support multiband signals, each amplifier is not only in-band noise, but also other multiplexing. Out-of-band noise for each of the bands may also be introduced.

  The DRx module E510 of FIG. 24 addresses some of these issues. The DRx module E510 includes a single pole / single throw (SPST) switch E519 that couples the first path to the second path. To operate in a single band mode for the first frequency band, switch E519 is opened, the first amplifier E514a is enabled, and the second amplifier E514b is disabled. That is, the single band signal in the first frequency band propagates from the antenna 140 along the first path to the transmission line 135 without switching loss. Similarly, to operate in single band mode for the second frequency band, switch E519 is opened, first amplifier E514a is disabled, and second amplifier E514b is enabled. That is, the single band signal in the second frequency band propagates from the antenna 140 along the second path to the transmission line 135 without switching loss.

  To operate in a multi-band mode for the first frequency band and the second frequency band, switch E519 is closed, first amplifier E514a is enabled, and second amplifier E514b is disabled. That is, the first frequency band portion of the multiband signal propagates along the first path that passes through the first phase shift component E527a, the first impedance matching component E526a, and the first amplifier E514a. The first frequency band portion is prevented from backpropagating along the second path across the switch E519 by the second phase shift component E527b. In particular, the second phase shift component E527a is configured to phase shift the first frequency band portion of the signal passing through the phase shift component E527b to maximize (or at least increase) the impedance in the first frequency band. The

  The second frequency band portion of the multiband signal propagates along a second path through the second phase shift component E527b, traverses the switch E519, and into the first path through the first impedance matching component E526a and the first amplifier E314a. Propagate along. The second frequency band portion is prevented from backpropagating along the first path by the first phase shift component E527a. In particular, the first phase shift component E527a is configured to phase shift the second frequency band portion of the signal passing through the first phase shift component E527a in order to maximize (or at least increase) the impedance in the second frequency band. Is done.

  Each path can be characterized by noise figure and gain. The noise figure of each path represents the signal-to-noise ratio (SNR) degradation caused by the amplifiers and impedance matching components E526a to E526b provided along the path. In particular, the noise figure of each path is the decibel (dB) difference between the SNR at the input of the impedance matching components E526a-E526b and the SNR at the output of the amplifiers E314a-E314b. That is, the noise figure is a measure of the difference between the noise output of an amplifier with the same gain and the noise output of an “ideal” amplifier (no noise is generated).

  The noise figure of each path can be different for different frequency bands. For example, the first path may have a first noise figure for the first frequency band and a second noise figure for the second frequency band. The noise figure and gain of each path (in each frequency band) may depend, at least in part, on the impedance (in each frequency band) of the impedance matching components E526a-E526b. Therefore, the impedance of the impedance matching components E526a-E526b may be advantageous to minimize (or reduce) the noise figure of each path.

The switching network includes a plurality of SPST switches that combine a plurality of paths corresponding to a plurality of frequency bands. In some implementations, when the band select signal indicates a single frequency band, the controller sends a switching signal that opens all of the SPST switches. In some implementations, when the band select signal indicates multiple frequency bands, the controller transmits a switching signal that closes one or more of the SPST switches to couple the paths corresponding to the multiple frequency bands.

  In block E740, the controller transmits a tuning signal to one or more tunable components based on the band selection signal.

In particular, the DRx module F610 may include one or more tunable matching circuits provided at one or more of the inputs and outputs of the DRx module F610.

  It is unlikely that all of the multiple frequency bands received at the same diversity antenna 140 are ideal impedance matching. To match each frequency band using a compact matching circuit, a tunable input matching circuit F616 is implemented at the input of the DRx module F610 and is configured by the DRx controller F602 (eg, based on a band selection signal from the communication controller). Controlled).

You may connect between.

  Similarly, depending on the transmission line 135 (or at least some cables) carrying signals in many frequency bands, it is unlikely that all multiple frequency bands will be an ideal impedance match. A tunable output matching circuit F617 is implemented at the output of the DRx module F610 to match each frequency band using a compact matching circuit (eg, based on a band selection signal from the communication controller) by the DRx controller F602.

You may connect between.

  FIG. 28 illustrates that, in some embodiments, diversity receiver configuration F700 can include multiple transmission lines. Although FIG. 28 illustrates one embodiment with two transmission lines F735a-F735b and one antenna 140, the aspects described herein may include more than two transmission lines and / or (further described below. Can be implemented in embodiments with two or more antennas.

  Diversity receiver configuration F700 includes a DRx module F710 coupled to antenna 140. The DRx module F710 is coupled to the input of the DRx module F710 (eg, the input coupled to the antenna 140a) and the output of the DRx module (eg, the first output coupled to the first transmission line F735a or the second transmission line F735b). A certain number of paths to the second output). In some implementations, the DRx module F710 includes one or more bypass paths (not shown) between inputs and outputs activated by one or more bypass switches controlled by the DRx controller F702.

  The DRx module F710 includes a fixed number of multiplexer paths including an input multiplexer F311 and an output multiplexer F712. The multiplexer path includes a fixed number of on-module paths (shown) including an input multiplexer F311, bandpass filters F313a-F313d, amplifiers F314a-F314d, and an output multiplexer F712. The multiplexer path may include one or more off-module paths (not shown) described herein. Again, as described herein, amplifiers F314a-F314d may be variable gain amplifiers and / or variable current amplifiers.

  The DRx controller F702 is configured to selectively activate one or more of the plurality of paths between the input and the output. In some implementations, the DRx controller F702 is configured to selectively activate one or more of the plurality of paths based on a band selection signal that the DRx controller F702 receives (eg, from a communication controller). Is done. DRx controller F702 may selectively activate the path, for example, by enabling or disabling amplifiers F314a-F314d, by controlling multiplexers F311, F712, or through other mechanisms described herein. it can.

  In order to make good use of the multiple transmission lines F735a to 735b, the DRx controller F702 controls the output multiplexer F712 based on the band selection signal to transmit each signal propagating along the path to the transmission lines F735a to F735b (or transmission). Can be routed to a selected one of the output multiplexer outputs corresponding to lines F735a-F735b.

  In some implementations, if the band select signal indicates that the received signal includes a single frequency band, the DRx controller F702 controls the output multiplexer F712 to direct the signal propagating on the corresponding path to the default transmission line. And can be routed. The default transmission line may be the same for all paths (and corresponding frequency bands), such as when one of the transmission lines F735a-F735b is short and the introduction of noise is low or otherwise not preferred. The default transmission line may be different for different paths. For example, a route corresponding to the low frequency band may be routed to the first transmission line F735b, and a route corresponding to the high frequency band may be routed to the second transmission line F735b.

  That is, the DRx controller F702 controls the second multiplexer F712 in response to a band selection signal indicating that one or more RF signals received at the input multiplexer F311 include a single frequency band. The amplified RF signal received at the output multiplexer input corresponding to the frequency band can be configured to be routed to the default output multiplexer output. As described herein, the default output multiplexer output may be different for different single frequency bands, or may be the same for all frequency bands.

  In some implementations, if the band select signal indicates that the received signal includes two frequency bands, the DRx controller F702 controls the output multiplexer F712 to route to the first frequency band. The signal propagating along can be routed to the first transmission line F735a, and the signal propagating along the path corresponding to the second frequency band can be routed to the second transmission line F735b. That is, when both of the two frequency bands are the high frequency band (or the low frequency band), the signal propagating along the corresponding path can be routed to different transmission lines. Similarly, when there are three or more transmission lines, each of the three or more frequency bands can be routed to different transmission lines.

  That is, the DRX controller F702 controls the second multiplexer F712 in response to a band selection signal indicating that one or more RF signals received at the input multiplexer F311 include the first frequency band and the second frequency band. Thus, the amplified RF signal received at the output multiplexer input corresponding to the first frequency band is routed to the first output multiplexer output, and the amplified RF signal received at the output multiplexer input corresponding to the second frequency band is It can be configured to route to a second output multiplexer output. As described herein, both the first frequency band and the second frequency band may be a high frequency band or a low frequency band.

  In some implementations, if the band select signal indicates that the received signal includes three frequency bands, the DRx controller F702 controls the output multiplexer F712 to provide two paths corresponding to two of the frequency bands. Two of the signals propagating along the line, routing the combined signal along one of the transmission lines, and passing the signal propagating along the path corresponding to the third frequency band along the other of the transmission line. Can be drawn around. In some implementations, the DRx controller F702 controls the output multiplexer F712 to combine two of the three frequency bands that are closest to each other (eg, both low frequency bands or both high frequency bands). Such an implementation can simplify impedance matching at the output of the DRx module F710 or at the input of the downstream module. In some implementations, DRx controller F702 controls output multiplexer F712 to combine the two furthest of the three frequency bands. Such an implementation can simplify the division of the frequency band in the downstream module.

  That is, the DRx controller F702 receives the second multiplexer in response to the band selection signal indicating that the one or more RF signals received at the input multiplexer F311 include the first frequency band, the second frequency band, and the third frequency band. F712 is controlled and (a) the amplified RF signal received at the output multiplexer input corresponding to the first frequency band is combined with the amplified RF signal received at the output multiplexer input corresponding to the second frequency band. Generating a combined signal; (b) routing the combined signal to the first output multiplexer output; and (c) the amplified RF signal received at the output multiplexer input corresponding to the third frequency band to the second output multiplexer output. It can be configured to be routed. As described herein, the first frequency band and the second frequency band may be the three frequency bands that are closest or farthest from each other.

  In some implementations, if the band select signal indicates that the received signal includes four frequency bands, the DRx controller F702 controls the output multiplexer F712 to provide two paths corresponding to two of the frequency bands. 2 of the signal propagating along the two paths corresponding to the other two of the frequency band, combining the two signals propagating along the first, routing the first combined signal along one of the transmission lines And the second combined signal can be routed along the other of the transmission lines. In some implementations, DRx controller F702 controls output multiplexer F712 to combine three of the signals propagating along three paths corresponding to three of the frequency bands, and combine the combined signal into the transmission line. , And a signal propagating along a path corresponding to the fourth frequency band can be routed along the other of the transmission lines. Such an implementation may be advantageous when three of the frequency bands are close to each other (eg, all are low frequency bands) and the fourth frequency band is separated (eg, high frequency bands).

  In general, if the band select signal indicates that the received signal includes more frequency bands than the existing transmission lines, the DRx controller F702 controls the output multiplexer F712 to accommodate two or more of the frequency bands. Two or more of the signals propagating along two or more paths can be combined and the combined signal can be routed to one of the transmission lines. The DRx controller F702 can control the output multiplexer F712 to combine the frequency bands that are closest or farthest from each other.

  That is, a signal propagating along one of the paths can be routed by the output multiplexer F712 to a different one of the transmission lines depending on other signals propagating along the other path. In one example, a signal propagating along a third path passing through the third amplifier F314c is routed to the second transmission line F735b if the third path is the only active path (fourth If the fourth path (through amplifier F314d) is also active, it is routed to the first transmission line F735a (and routed to the second transmission line 735b).

  That is, the DRx controller F702 controls the output multiplexer F712 in response to the first band selection signal to route the amplified RF signal received at the output multiplexer input to the first output multiplexer output for the second band selection. Controlling the output multiplexer in response to the signal routes the amplified RF signal received at the output multiplexer input to the second output multiplexer output.

  That is, the DRx module F710 constitutes a reception system including a plurality of amplifiers F314a to F314d, and each one of the plurality of amplifiers F314a to F314d is input to the reception system (for example, the input of the DRx module F710 coupled to the antenna 140). And / or additional inputs of the DRx module F710 coupled to other antennas) and the output of the receiving system (eg, the output of the DRx module F710 coupled to the transmission lines F735a-F735b, and / or other transmission lines). Are provided along a corresponding one of a plurality of paths between the combined output of the DRx module F710). Amplifiers F314a-F314d are each configured to amplify the RF signal received at amplifiers F314a-F314d.

  The DRx module F710 further includes an input multiplexer F311. This receives one or more RF signals at one or more input multiplexer inputs and outputs each of the one or more RF signals to one or more of a plurality of input multiplexer outputs to each one or more of a plurality of paths. Configured to propagate along. In some implementations, the DRx module F710 receives a single RF signal at a single input multiplexer input, and inputs the single RF signal to one of the input multiplexer outputs corresponding to each frequency band indicated in the band select signal. The output can be controlled by the DRx controller F702. In some implementations, the DRx module F710 receives multiple RF signals (each corresponding to one or more different frequency bands indicated in the band selection signal) at the multiple input multiplexer input and Each may be controlled by DRx controller F702 to output to one or more of the input multiplexer outputs corresponding to the set of one or more frequency bands of the RF signal. That is, in general, the input multiplexer F311 receives one or more RF signals each corresponding to one or more frequency bands, and sends each RF signal to one or more paths corresponding to one or more frequency bands of the RF signal. Controlled by the DRx controller to route along.

  The DRx module F710 further includes an output multiplexer F712. This receives one or more amplified RF signals propagating along one or more of each of a plurality of paths at one or more corresponding output multiplexer inputs, and each of the one or more amplified RF signals is output to a plurality of outputs. Output to a selected one of the multiplexer outputs (each coupled to one of a plurality of output transmission lines F735a-F735b).

  The DRx module F710 further includes a DRx controller F702 configured to receive a band selection signal and control an input multiplexer and an output multiplexer based on the band selection signal.

Other diversity receiver configurations may include a first antenna F1040a that supports a low frequency band and a second antenna F1040b that supports an intermediate frequency band and a high frequency band. Still other diversity receiver configurations include a first wideband antenna F1040a that supports a low frequency band, an intermediate frequency band, and a high frequency band, and the second antenna F1040b may be absent.

By controlling the input multiplexer F1011 the same DRx module F1010 can be used.

  In some implementations, if the antenna configuration signal indicates that the diversity receiver configuration F1000 includes only a single antenna F1040a, the DRx controller F1002 received at the single antenna F1040a by controlling the input multiplexer. The signal can be routed to all of the paths (or all of the active paths indicated by the band select signal).

To all of the input multiplexer outputs or to all of the plurality of input multiplexer outputs associated with one or more frequency bands of the RF signal.

  In some implementations, the antenna configuration signal indicates that the diversity receiver configuration F1000 includes a first antenna F1040a that supports a low frequency band and a second antenna F1040b that supports an intermediate frequency band and a high frequency band.

When the antenna configuration signal indicates, the DRx controller F1002 controls the input multiplexer F1011 to route the signal received at the first antenna F1040a to the first path and the second path, and at the second antenna F1040b. The received signal can be routed to the third and fourth paths, or at least those paths that are active as indicated by the band select signal.

The DRx controller F1002 controls the input multiplexer F1011 to route the signal received at the first antenna F1040a to the first path, the second path, and the third path, and the signal received at the second antenna F1040b. A fourth path, or at least those paths that are active as indicated by the band select signal, can be routed.

  That is, the signal propagating along a particular path (eg, the third path) is received from the different one of the input multiplexer inputs (coupled to one of the antennas F1040a to F1040b) by the input multiplexer F1011 (antenna configuration signal).

In one example, the input multiplexer F1011 and the bandpass filters F313a to F313d constitute such a band divider. In other implementations (as described further below), bandpass filters F313a-F313d and input multiplexer F1011 may be integrated in other manners to form a band divider.

The second input F1201b is coupled to the first MPST switch F1230a, the second MPST switch F1230b, and the fourth output F1202d. The switches F1230a-F1230b are controllable via a control bus F1203 that can be coupled to a DRx controller.

  Unlike the input multiplexer F1111 of FIG. 32, the output multiplexer F1211 of FIG. 33 does not allow each of the inputs F1201a to F1201b to be routed to any of the outputs F1202a to F1202d. Rather, the first input F1201a is fixedly routed to the first output F1202a, and the second input F1201b is fixedly routed to the fourth output F1202d. Such an implementation can reduce the size of the control bus F903 or simplify the control logic of the DRx controller attached to the control bus F903. Nevertheless, the DRx controller controls the switches F1230a to F1230b on the basis of the antenna configuration signal so that the signal from any of the inputs F1201a to F1201b is sent to the second output F1202b and / or the third output F1202c. And can be routed.

  Both the input multiplexer F1111 in FIG. 32 and the input multiplexer F1211 in FIG. 33 operate as a multi-pole / multi-throw (MPMT) switch.

In some implementations, the band select signal indicates more frequency bands than there are available output terminals, and the controller combines two or more of the frequency bands (ie, the same for two or more frequency bands). Determine the output terminal. The controller can decide to combine the closest frequency band or the most distant frequency band.

  In block F1430, the controller controls the output multiplexer to route the signal for each frequency band to the determined output terminal. The controller can control the output multiplexer by opening or closing one or more SPST switches, determining the state of one or more SPMT switches, sending an output multiplexer control signal, or by other mechanisms.
