Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

With the continuous development of GSM communication technology, the large-scale construction of GSM network is becoming more and more mature. The GSM network can be configured with four frequency bands, GSM850, GSM900, DCS1800 and PCS1900, referred to as "GSM quad-band". In a GSM network, the performance of radio frequency indicators can be measured by ORFS; wherein, ORFS can be further divided into GSM modulation spectrum (Spectrum due to Modulation) and switching spectrum (Spectrum due to Switching). Here, the GSM modulation spectrum refers to the spectrum generated in the adjacent frequency band after the digital bit information is modulated, mainly to prevent out-of-band spectrum radiation and avoid the interference of adjacent channels; The radio frequency spectrum generated on the adjacent frequency band of the frequency, that is, the radio frequency power at different offsets of its nominal carrier frequency (mainly in adjacent channels) due to the rising and falling edges of the modulation burst, the main purpose is to prevent The switching pulses during frequency band switching cause interference to adjacent channels.

Referring to FIG. 1 , it shows a schematic structural diagram of a conventional radio frequency circuit provided by an embodiment of the present application. As shown in FIG. 1 , the conventional radio frequency circuit 10 may include a wireless transceiver (WTR) 110 , a power amplifier (PA) 120 , a filter (filter) 130 , and an antenna switch module (ASM). ) 140, a coupler (couple) 150 and an antenna (Antenna, ANT) 160; wherein, the wireless transceiver 110 may include a feedback receiver (Feedback Receiver, FBRX) 1101, a crystal oscillator (Crystal Oscillator, XO) 1102 and a digital Analog conversion (Digital to Analog, DA) 1103. In this way, when the GSM network is working, the wireless transceiver 110 outputs the GSM transmission signal through the DA port, the transmission signal is amplified by the power amplifier 120 to obtain the transmission power of the transmission signal, and then passes through the filter 130 and the antenna in sequence The switch module 140 reaches the coupler 150, and finally the transmission signal is transmitted outward from the antenna 160 according to the obtained transmission power, thereby forming a transmission chain. In this process, since the transmit power will leak at the coupler 150, the leaked power will leak to the FBRX port along the coupling link, and then continue to leak to the XO and DA from the FBRX inside the wireless transceiver 110, As a result, the performance of the ORFS radio frequency indicators is abnormal. For example, taking a manufacturer's MSM8953+MTR2965 platform as an example, when GSM transmits at maximum power, its ORFS RF performance is very poor, bordering the 3GPP standard, and the abnormal frequency is located at the XO 19.2MHz multiplier.

Specifically, based on the conventional radio frequency circuit shown in FIG. 1 , the transmit power will leak along the coupling path indicated by the dashed arrow direction. When the wireless transceiver 110 outputs the GSM transmit signal through the DA port, the transmit signal is amplified by the power amplifier 120 to obtain the transmit power, and then reaches the coupler 150 through the filter 130 and the antenna switch module 140 in sequence. The transmit power will be transmitted through the antenna 160; however, a small part of the transmit power will leak into the FBRX along the coupling link, and then continue to leak to the XO and DX outputs, thereby forming spurious and seriously affecting the performance of the ORFS radio frequency index.

The existing solution is to add an attenuation network on the coupling link in Figure 1, and reduce the power leakage of the GSM transmit power on the coupled link through the attenuation network, reduce interference, and improve the performance of the ORFS radio frequency index. As shown in FIG. 2 , on the basis of the conventional radio frequency circuit shown in FIG. 1 , the conventional radio frequency circuit 10 may further include an attenuation network 170 . The attenuation network 170 can attenuate the leaked transmit power, thereby reducing the leakage of the GSM transmit power, and can achieve the purpose of improving the performance of the ORFS radio frequency index. However, this solution has great limitations. On the one hand, since the FBRX port has a dynamic receiving range, when the attenuation network is large, it will affect the detection accuracy of the FBRX, resulting in abnormal power control; on the other hand, This solution can only improve the performance of the ORFS radio frequency index relatively, and the interference still exists; although the performance of the ORFS radio frequency index has been improved and can meet the 3GPP standard, the margin is small, so that with the increase of GSM transmit power, the performance There is still a risk of fail.

The embodiment of the present application provides a performance optimization method, and the method is applied to a performance optimization apparatus, and the performance optimization apparatus is located in a terminal device. By determining the working mode of the terminal device; wherein, the working mode includes a first working mode and a second working mode, the first working mode is that the terminal device is in GSM mode, and the second working mode is that the terminal The device is in a mode other than the GSM mode; according to the determined work mode, the switch is controlled to be in a corresponding connection state; wherein the first work mode corresponds to the first connection state of the switch, and the second work mode The mode corresponds to the second connection state of the switch; when the working mode is the first working mode, grounding processing is performed through the first connection state of the switch to optimize the radio frequency performance of the terminal device; in this way , not only can ensure the detection accuracy of FBRX and avoid the problem of abnormal power control; but also can improve the ORFS radio frequency performance of GSM, so that it fully meets the enterprise standard, and at the same time reduces the risk of performance failure.

In the embodiment of the present application, the switch is usually selected as a single-pole double-throw switch.

In order to optimize the radio frequency performance of the terminal device, in some embodiments, the switch is located in a coupling link; wherein the direction of the coupling link is opposite to the direction of the transmitting link.

It should be noted that in order to reduce the power leakage of the terminal equipment and improve the radio frequency performance of the terminal equipment, it is necessary to increase the isolation between the transmit link port and the FBRX port. accomplish. Among them, according to the traditional radio frequency circuit shown in FIG. 2 , the transmission chain is that after the transmission signal is output from the DA port in the wireless transceiver 110 , the transmission signal passes through the power amplifier 120 , the filter 130 , the antenna switch module 140 and the coupler 150 in sequence. The formed link is finally transmitted through the antenna 160; the coupling link is the link formed between the coupler 150 and the FBRX port in the wireless transceiver 110, and the directions of the two are opposite; thus, in the coupling link By adding a switch on the top of the switch, the isolation between the transmit link port and the FBRX port can be increased by controlling the connection state of the switch, thereby reducing the power leakage of the terminal device and optimizing the radio frequency performance of the terminal device.

S303: When the working mode is the first working mode, perform grounding processing through the first connection state of the switch to optimize the radio frequency performance of the terminal device.

It should be noted that when the working mode is the first working mode, there is no need to perform power detection on the terminal device at this time, and the switch can be switched to the first connection state; when the working mode is the second working mode, it needs to be Perform power detection on the terminal device, at this time, the switch can be switched to the second connection state; in this way, when the terminal device is in the first working mode, such as GSM mode, the switch is in the first connection state, and the switching can be increased by grounding processing. The isolation degree of the switch increases the isolation degree between the transmitting chain port and the feedback receiver port, thereby reducing the power leakage of the terminal equipment and realizing the optimization of the radio frequency performance of the terminal equipment, such as improving the ORFS radio frequency index. performance.

In some embodiments, the switch is a single-pole double-throw switch; wherein the switch includes a first terminal, a second terminal and a third terminal; wherein the third terminal and the switch The knife of the switch is connected.

It should be noted that, because the SPDT switch includes three terminals, and the third terminal is connected to the pole of the switch. Wherein, the switch can realize two connection states (including the first connection state and the second connection state) of the switch by closing the knife to the first terminal or the second terminal. However, the connection method of the switch in the coupling link can be different, resulting in different grounding processing methods; for example, the feedback receiver port can be grounded, or the RF link port can be grounded; the following will be combined with Figure 4 Or the improved radio frequency circuit shown in FIG. 5 will be described in detail.

Referring to FIG. 4 , it shows a schematic diagram of the composition and structure of an improved radio frequency circuit provided by an embodiment of the present application. As shown in FIG. 4, compared with the conventional radio frequency circuit 10, the improved radio frequency circuit 20 may further include a switch 210, wherein the switch 210 is a single-pole double-throw switch, which includes a first terminal (represented by 1), The second terminal (denoted by 2) and the third terminal (connected to the knife).

It should be noted that the port of the transmit link can be the port of the attenuation network or the port of the coupler (when there is no attenuation network in the coupling link, the third terminal of the switch can be directly connected to the port of the coupler) , and may also be the port of other devices in the coupling link; in practical application, it is determined according to the actual circuit situation and the principle of nearest connection, which is not specifically limited in this embodiment of the present application. In Figure 4, the transmit link ports represent the ports on the side of the attenuation network.

It should also be noted that when the terminal device is in the first working mode, such as GSM mode, it is not necessary to perform power detection through the feedback receiver port at this time, and the second terminal of the switch can be connected to the third terminal. The knife of the switch is closed to the second terminal), so that it is in the first connection state, which also realizes the grounding processing method of the feedback receiver port, which can increase the distance between the feedback receiver port and the transmitting link port. The isolation degree of the terminal device is reduced, thereby reducing the power leakage of the terminal device; when the terminal device is in the second working mode, such as other modes except the GSM mode, power detection needs to be performed through the feedback receiver port at this time. The first terminal of the switch is connected to the third terminal (that is, the knife of the switch is closed to the first terminal), so that it is in the second connection state, which also realizes the normal power detection of the terminal device.

The isolation between the network side and the FBRX port reduces the power leakage of the terminal equipment, which can achieve the purpose of optimizing the radio frequency performance of the terminal equipment, such as improving the ORFS radio frequency performance of GSM; when the terminal equipment is in other modes and the GSM mode When it is not working, it is necessary to perform power detection through the FBRX port at this time, and the knife of the switch 210 can be controlled to close to 1, and the FBRX port is connected to the attenuation network side, so as to realize the normal power detection of the terminal equipment; in this way, through a The switch can perfectly solve the problem of power leakage in GSM mode, thereby optimizing the radio frequency performance of the terminal device.

Referring to FIG. 5 , it shows a schematic diagram of the composition and structure of another improved radio frequency circuit provided by an embodiment of the present application. As shown in FIG. 5 , the connection manner of the switch 210 is different from the connection manner of the switch 210 in FIG. 4 . In FIG. 5, the third terminal of the switch 210 is connected to the attenuation network, the first terminal of the switch 210 is connected to the FBRX port, and the second terminal of the switch 210 is connected to ground; thus, the first terminal of the switch 210 is connected to the ground; A connection state is that the third terminal is connected to the second terminal (ie, the switches of the switch 210 are closed to 2), and the second connection state of the switch 210 is that the third terminal is connected to the first terminal (ie, the switch The knife of 210 is closed to 1).

Based on the improved radio frequency circuit shown in FIG. 5 , in yet another embodiment of the present application, the first terminal is connected to the feedback transceiver port, the second terminal is connected to ground, and the third terminal is connected to the ground. Connect to the transmission link port; for S302, the controlling the switch to be in a corresponding connection state according to the determined working mode may include:

S302b-1: When the working mode is the first working mode, control the switch to be in a first connection state, and connect the transmission link port to the ground; wherein, the first connection state is the connection state of the switch the knife is closed to the second terminal;

S302b-2: When the working mode is the second working mode, control the switch to be in a second connection state, and connect the feedback receiver port to the transmission link port; wherein the second connection state is the The knife of the switch is closed to the first terminal.

Further, in some embodiments, for S303, when the working mode is the first working mode, the grounding process is performed through the first connection state of the switch, and the radio frequency performance of the terminal device is affected. To optimize, can include:

S303b-1: When the working mode is the first working mode, connect the transmit link port to the ground through the first connection state of the switch, and add the feedback receiver port and the transmit link isolation between ports to optimize the RF performance of the end device.

Further, in some embodiments, the method may also include:

S303b-2: When the working mode is the second working mode, connect the feedback receiver port to the transmission link port through the second connection state of the switch to implement power detection of the terminal device .

It should be noted that the port of the transmit link can be the port of the attenuation network or the port of the coupler (when there is no attenuation network in the coupling link, the third terminal of the switch can be directly connected to the port of the coupler) , and may also be the port of other devices in the coupling link; in practical application, it is determined according to the actual circuit situation and the principle of nearest connection, which is not specifically limited in this embodiment of the present application. In Figure 5, the transmit link ports still represent the ports on the attenuating network side.

It should also be noted that when the terminal device is in the first working mode, such as GSM mode, it is not necessary to perform power detection through the feedback receiver port at this time, and the second terminal of the switch can be connected to the third terminal. The knife of the switch is closed to the second terminal), so that it is in the first connection state, which also realizes the grounding processing method of the transmitting link port. This grounding processing method can also increase the difference between the feedback receiver port and the transmitting link port. Therefore, the power leakage of the terminal device is reduced; when the terminal device is in the second working mode, such as other modes other than the GSM mode, power detection needs to be performed through the feedback receiver port, which can be The first terminal of the switch is connected to the third terminal (that is, the knife of the switch is closed to the first terminal), so that it is in the second connection state, which also realizes the normal power detection of the terminal device.

Taking FIG. 5 as an example, the third terminal of the switch 210 is connected to the blade, and the third terminal is connected to the attenuation network; the first terminal of the switch 210 is represented by 1, and the first terminal is connected to the FBRX port; The second terminal of the switch 210 is denoted by 2, and the second terminal is connected to ground; here, the first connection state of the switch 210 is that the third terminal is connected to the second terminal (ie, the blade of the switch 210 is closed. to 2), the second connection state of the switch 210 is that the third terminal is connected to the first terminal (ie, the knife of the switch 210 is closed to 1). In this way, when the terminal device is in the GSM mode, it is not necessary to perform power detection through the FBRX port at this time, and the switches of the switch 210 can be controlled to be closed to 2 positions, and the attenuation network side is directly connected to the ground, that is, the radio frequency link port is realized. Grounding processing. This grounding processing method can also increase the isolation between the transmitting link port and the FBRX port, thereby reducing the power leakage of the terminal equipment, and optimizing the radio frequency performance of the terminal equipment. When the terminal device is in other modes and the GSM mode does not work, the power detection needs to be performed through the FBRX port, and the knife of the switch 210 can be controlled to be closed to 1, and the FBRX port is connected to the attenuation network side, thereby The normal power detection of the terminal equipment is realized; in this way, through a switch, the problem of power leakage in the GSM mode can be perfectly solved, thereby optimizing the radio frequency performance of the terminal equipment.

In practical applications, taking a manufacturer as an example, it is assumed that the minimum power requirement received by the feedback receiver is -15dBm. The leakage power is at least 10dB lower than -15dBm. In this way, assuming that the transmit power of GSM is 33dBm, the coupling factor of the coupler is 23dB, and the attenuation network is 6dB, then by calculation, 33dBm-23dB-6dB=4dB, which is completely unsatisfactory. At this time, according to the existing solution, it can be improved by adding an attenuation network, but when the attenuation network is too large, the power detection range of the feedback receiver port will be exceeded, thereby reducing the power detection accuracy of the feedback receiver port. For example, assuming that the transmit power is 23dBm and the coupling factor of the coupler is 23dB, when the attenuation network exceeds 15dB, although the power leakage is reduced, it will affect the power detection of the feedback receiver port, that is, the two are a contradictory process, and existing solutions do not better address the problem.
