In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

An embodiment of the present invention provides a radio frequency transceiver, which is applied to a terminal, the terminal includes a main receiving system and at least one auxiliary receiving system, the radio frequency transceiver includes a radio frequency transceiver chip, and it is characterized in that the main receiving system The system includes a main antenna connected in sequence, a main receiving module, and the radio frequency transceiver, the auxiliary receiving system includes an auxiliary antenna and an auxiliary receiving module connected in sequence, and the radio frequency transceiver also includes: a signal processing module, connected with the radio frequency The transceiver chips are connected and used to synchronously receive the signals sent by the main receiving module and the auxiliary receiving module corresponding to the idle auxiliary antenna, synthesize the received multiple signals into one signal and output it to the radio frequency transceiver chip.

Specifically, the auxiliary receiving module includes an antenna switch, a matching circuit, and a filter connected in sequence, wherein: the matching circuit is used to match the auxiliary antenna corresponding to the auxiliary receiving module, and transmit the auxiliary antenna to the filter. The signal received by the antenna; the filter is used to filter the signal sent by the matching circuit and output it to the signal processing module.

It should be noted that the main receiving system mentioned in the embodiments of the present invention refers to the system corresponding to the current signal to be received. For example, if the currently received signal is a WCDMA signal, the current main receiving system is a WCDMA system. If the signal is a Bluetooth signal, the current main receiving system is the Bluetooth system, and the main receiving system and the auxiliary receiving system in this embodiment are not fixed.

When the signal received by the main antenna is a Wideband Code Division Multiple Access (WCDMA) signal or a Code Division Multiple Access (CDMA) signal, the main receiving module includes an antenna located between the main antenna and the signal processing module switches and duplexers.

The above-mentioned radio frequency transceiver adopts the multiplex receiving mode to receive base station signals synchronously, realizes multi-path reception, and greatly improves the transmission speed and signal reception strength of received signals.

As shown in Figure 2, it is a schematic diagram of the mobile phone radio frequency architecture of the WCDMA mobile phone terminal embodiment of the present invention. In this embodiment, each system no longer exists independently, but uses its idle antenna when the Bluetooth, WIFI, and GPS systems are idle. 1. The receiving system is used as an auxiliary receiving system of the WCDMA receiving system or forms a diversity receiving system. The WCDMA system is to receive signals from the main antenna 1, through the antenna switch 4 to the duplexer 8, and then to the signal processing module 11 and then enter the radio frequency transceiver module 12; During signal processing, signal transmission behavior), after the Bluetooth antenna 2 receives the WCDMA signal, it no longer passes through the Bluetooth matching circuit 14 but switches to a new antenna matching circuit 13 through the antenna switch 5 (this matching circuit is to enable the Bluetooth antenna to receive WCDMA signal), and then enter the signal processing module 11 through the filter 9 (this signal processing module is used to process several channels of received signals, process, integrate, and combine the signals into one signal), and then the signal enters the radio frequency transceiver Processing module 12; WIFI, GPS system receive WCDMA signal behavior similar to bluetooth system, receive signal through respective antenna through antenna switch, enter signal processing module 11 after new matching circuit, filter, signal processing module processes and integrates the signal Then enter the radio frequency transceiver processing module 12. The signal processing module 11 and the radio frequency transceiver processing module 12 are included in the improved radio frequency transceiver chip, that is, signal integration and transceiver processing are all performed inside the chip.

To sum up, the above-mentioned multiplexing reception architecture is to integrate WCDMA and other radio frequency receiving systems, and use other radio frequency receiving systems as auxiliary receiving systems of WCDMA to receive signals with multi-channel diversity. When other radio frequency systems are idle, use their antenna to receive WCDMA signals, pass through the antenna switch, pass through a new matching circuit (this matching circuit is used to match Bluetooth, WIFI, GPS antennas to receive WCDMA signals), and then pass through a filter (filter out WCDMA needs to receive the noise signal outside the frequency band signal), and then several signals and the signal received by the WCDMA system itself are synthesized into one signal through the signal processing module, and enter the WCDMA radio frequency transceiver module for signal processing.

In addition, when the signal received by the main antenna is a signal other than a WCDMA signal and a CDMA signal such as a Bluetooth signal, the main receiving module includes an antenna switch and an antenna between the main antenna and the signal processing module.

Usually, the antenna of WCDMA will not be in an idle state, therefore, for the Bluetooth or WIFI system, only idle systems other than WCDMA can be used to receive signals synchronously. Of course, it is also possible for the WCDMA system to use time division technology to receive signals synchronously with other main receiving systems. It is a multi-band antenna or broadband antenna for different applications.

The terminal including the above-mentioned radio frequency transceiver adopts the multiplexing receiving method to receive the base station signal synchronously through the main receiving system and the auxiliary receiving system, realizes multi-path receiving, and greatly improves the transmission speed and signal receiving strength of the received signal.

When the signals received by the main antenna are signals other than WCDMA signals and CDMA signals, the main receiving module includes an antenna switch, an antenna matching circuit and other peripherals located between the main antenna and the signal processing module circuits, at this time, there are at least two secondary receiving systems in the terminal.

As shown in Figure 3, the second schematic diagram of the mobile phone radio frequency architecture of the WCDMA mobile phone terminal embodiment of the present invention, the radio frequency framework in this embodiment is basically consistent with the mobile phone radio frequency architecture shown in Figure 2, the difference is that the improved radio frequency transceiver chip integrates the filter circuit , the signal received by the auxiliary receiving system or the diversity receiving system does not need to be filtered, and directly enters the signal processing module of the RF transceiver chip for integration processing, and then passes through the internal filtering module for filtering processing, which saves the use of external filters and integrates higher degree.

The above are the two radio frequency architectures of mobile phone terminals with composite reception. The purpose is to make full use of the Bluetooth, WIFI, and GPS systems in the idle state, and integrate their antennas and receiving systems to make them an auxiliary receiving system for mobile phone network communications or form diversity.
