For convenience of description, the above-mentioned devices are collectively referred to as communication devices.

Fig. 1 is one of schematic structural diagrams of a radio frequency PA Mid device according to an embodiment, and referring to fig. 1, in one embodiment, the radio frequency PA Mid device is configured with a first input port 4G HB RFIN, a plurality of first output ports LNA OUT, and a plurality of second output ports LNA OUT MHB for connecting to a radio frequency transceiver, and the radio frequency PA Mid device includes a first transceiver module 110 and a first receiver module 120. Wherein the first transceiver module 110 is configured to support a transmission process, a main set reception process, and a main set MIMO reception process for the first target signal, and the first receiver module 120 is configured to support a diversity reception and a diversity MIMO reception process for the first target signal. The first target signal is a medium-high frequency signal of a first system. In each embodiment of the present application, the first system is exemplified by a 4G system and a 5G system.

Specifically, the first transceiver module 110 is connected to the first input port 4G HB RFIN and the first output port LNA OUT, specifically, the first output ports LNA OUT1 and LNA OUT2, respectively. The first transceiver module 110 is configured to support transmission processing of a first target signal from the first input port 4G HB RFIN, and transmit the processed signal to the first antenna ANT1. The first transceiver module 110 is further configured to support a main set receiving process of the first target signal from the first antenna ANT1, and transmit the processed signal to a first output port LNA OUT. The first transceiver module 110 is further configured to support a main set MIMO receiving process for the first target signal from the third antenna ANT3, and transmit the processed signal to another first output port LNA OUT. Illustratively, referring to fig. 1, two ports are connected to the right side of the first transceiver module 110, and the first transceiver module 110 may transmit signals to the first antenna ANT1 and the third antenna ANT3 via the two ports, respectively. However, it should be noted that the above two ports are only for illustration, and are not intended to limit the protection scope of the present embodiment, and the first transceiver module 110 may also transmit signals to the first antenna ANT1 and the third antenna ANT3 through other numbers of ports or other configurations.

The first transceiver module 110 includes at least one Power Amplifier (PA) and at least two low noise amplifiers (Low Noise Amplifier, LNA), and may further include at least one of a filter, a combiner, a duplexer, a switch, and the like, to support more complex transmit and receive processing functions. Through the first transceiver module 110 integrally arranged, the radio frequency PA Mid device can perform main set and main set MIMO receiving processing on the medium-high frequency signals of the first system on the premise of not arranging an external receiving module, so that the number of external wires is reduced, and the integration level of the radio frequency system is improved.

It should be noted that, although some ports are named in the 4G format in fig. 1, the ports may be used to transmit signals in the 5G format. Further, in order to improve the processing performance of the radio frequency PA Mid device on the medium-high frequency signals of the 4G system signals, the radio frequency PA Mid device in the embodiment of the application can also process the medium-frequency signals and the high-frequency signals of the 4G system respectively. The medium-high frequency signals may include intermediate frequency signals and high frequency signals among the 4G LTE signal, the 5G NR signal. The intermediate frequency signal may include radio frequency signals of at least one intermediate frequency band, for example, radio frequency signals of bands including B1, B3, B66, B25, B34, B39, and the like. The high frequency signals may include radio frequency signals of at least one high frequency band, such as radio frequency signals of bands including B7, B40, B41, etc. Accordingly, the radio frequency PA Mid device may be configured with two first input ports, referred to as 4G MB RFIN and 4G HB RFIN, respectively, to transmit signals of different frequency ranges, respectively.

Alternatively, the first transceiver module 110 may output the signals of different frequency bands after the transmission processing to the first antenna ANT1 through different ports, so as to transmit the medium-high frequency signals of different frequency bands. Therefore, a plurality of signal transmission paths may be formed between the first transceiver module 110 and the first antenna ANT1, and each signal transmission path is configured to transmit signals in different frequency bands, so as to expand the frequency band range that the rf PA Mid device can process. In addition, on each signal transmission path, a filter of a corresponding frequency band can be respectively arranged, so that the signals transmitted by the signal transmission paths are subjected to filtering processing, only the signals which are required to be transmitted by the signal transmission path where the signal transmission path is positioned are allowed to pass through, and other signals which are not required to be transmitted by the signal transmission path are isolated, so that the signals of different frequency bands are subjected to filtering processing respectively, and the signal transmission quality is improved.

The first receiving module 120 is connected to the second output port LNA OUT MHB, specifically to the second output ports LNA OUT MHB1 and LNA OUT MHB2, respectively. The first receiving module 120 is configured to support diversity reception processing of the first target signal from the second antenna ANT2, and transmit the processed signal to a second output port LNA OUT MHB. The first receiving module 120 is further configured to support diversity MIMO receiving processing of the first target signal from the fourth antenna ANT4, and transmit the processed signal to another second output port LNA OUT MHB. The first receiving module 120 includes at least two low noise amplifiers (Low Noise Amplifier, LNA), and may further include at least one of a filter, a combiner, a duplexer, a switch, and the like to support more complex receiving processing functions. Through the first receiving module 120, the rf PA Mid device can perform diversity and diversity MIMO receiving processing on the intermediate-high frequency signal of the first system without setting an external receiving module, thereby reducing the number of external wires and improving the integration level of the rf system.

In this embodiment, the rf PA Mid device includes a first transceiver module 110 and a first receiver module 120. The first transceiver module 110 is configured to support transmission processing of a first target signal from the first input port 4G HB RFIN, main set reception processing of the first target signal from the first antenna ANT1, and main set MIMO reception processing of the first target signal from the third antenna ANT 3. The first receiving module 120 is configured to support diversity reception processing of the first target signal from the second antenna ANT2 and diversity MIMO reception processing of the first target signal from the fourth antenna ANT 4. Thereby enabling transmission of the first target signal and 4 x 4 MIMO reception. Compared with a radio frequency PA Mid device which can only support 2 x 2MIMO receiving of the first target signal in the related art, the downlink speed can be doubled, the downlink coverage distance can be doubled, and the channel capacity and the receiving performance of a radio frequency system can be doubled.

Fig. 2 is a second schematic structural diagram of an embodiment of the rf PA Mid device, referring to fig. 2, IN one embodiment, the rf PA Mid device is further configured with a first auxiliary port LNA IN and a first Mid-high frequency antenna port ANT1 for connecting to the first antenna ANT1. The first transceiver module 110 includes a plurality of first low noise amplifiers 111.

Specifically, when the first transceiver module 110 includes only two first low noise amplifiers 111, the main set and main set MIMO receiving processes may be performed on the first target signals of the same frequency band. That is, when the main set and main set MIMO receiving processes are required for the first target signals of the plurality of frequency bands, a greater number of the first low noise amplifiers 111 may be provided, or the same first low noise amplifier 111 may be caused to process the first target signals of different frequency bands at different times, respectively. In addition, the rf PA Mid device is further configured with HB TX OUT ports for outputting the first target signal after the transmission process, and the first transceiver module 110 includes power amplifiers connected to the first input ports 4G HB RFIN, HB TX OUT ports, respectively, to perform the transmission process on the first target signal.

In this embodiment, by providing the plurality of first low noise amplifiers 111 in the first transceiver module 110, which are independent of each other, the main set and the main set MIMO receiving process of the first target signal can be implemented, and interference between different radio frequency channels can be avoided, so that a radio frequency PA Mid device with fast receiving rate and high signal reliability is implemented.

Taking the first transceiver module 110 as an example, the first transceiver module includes three first low noise amplifiers 111, an input terminal of one of the first low noise amplifiers 111 is connected to a first terminal of the first radio frequency switch 210, so as to support a main set receiving process of the first target signal from the first frequency band of the first mid-high frequency antenna port ANT 1. The input terminal of the other one of the first low noise amplifiers 111 is connected to the other one of the first terminals of the first rf switch 210 to support the main set receiving process of the first target signal from the second frequency band of the first mid-high frequency antenna port ANT 1. The remaining one of the inputs of the first low noise amplifier 111 is connected to a first auxiliary port MB LNA IN to support a main set MIMO reception process of the first target signal from the first frequency band of the first auxiliary port MB LNA IN. It is to be understood that the first rf switch 210 may also be connected to other signal transmission paths to transmit other signals to the first mid-high frequency antenna port ANT1 for transceiving, which is not limited in this embodiment.

The first receiving module 120 includes a plurality of second low noise amplifiers 121. Wherein an input end of at least one of the second low noise amplifiers 121 is connected to the second mid-high frequency antenna port MHB ANT to support diversity reception processing of the first target signal from the second mid-high frequency antenna port MHB ANT, an input end of at least another one of the second low noise amplifiers 121 is connected to the second auxiliary port LNA AUX MHB to support diversity MIMO reception processing of the first target signal from the second auxiliary port LNA AUX MHB, and output ends of a plurality of the second low noise amplifiers 121 are respectively connected to a plurality of the second output ports LNA OUT MHB in one-to-one correspondence.

Specifically, when the first receiving module 120 includes only two second low noise amplifiers 121, diversity and diversity MIMO receiving processes can be performed on the first target signal of the same frequency band. That is, when diversity and diversity MIMO reception processing is required for the first target signals of a plurality of frequency bands, a greater number of the second low noise amplifiers 121 may be provided, or the same second low noise amplifier 121 may be caused to process the first target signals of different frequency bands at different times, respectively. Also, similar to the first rf switch 210, when diversity and diversity MIMO reception processing is required for the first target signals of the multiple frequency bands, the rf PA Mid device may further include an SPnT switch, a plurality of first ends of which are connected to the plurality of second low noise amplifiers 121, respectively, and a second end of which is connected to the second Mid-high frequency antenna port MHB ANT (not shown). Taking the example that the first receiving module 120 includes two second low noise amplifiers 121, an input end of one of the second low noise amplifiers 121 is connected to a second mid-high frequency antenna port MHB ANT to support diversity receiving processing from the second mid-high frequency antenna port MHB ANT. The other input of the second low noise amplifier 121 is connected to a second auxiliary port LNA AUX MHB to support diversity MIMO reception processing of the first target signal from the second auxiliary port LNA AUX MHB.

In this embodiment, by providing a plurality of second low noise amplifiers 121 in the first receiving module 120, diversity and diversity MIMO receiving processing on the first target signal can be achieved, and interference between different radio frequency paths can be avoided, so that a radio frequency PA Mid device with fast receiving rate and high signal reliability is achieved.
