The first switch unit 100 includes a plurality of first terminals and a plurality of second terminals, and the plurality of second terminals of the first switch unit 100 are respectively connected to the plurality of antenna ports in a one-to-one correspondence manner. Specifically, the number of the first terminals of the first switch unit 100 is the same as the total number of the transmitting circuit 220 and the first receiving circuit 210 in the radio frequency PA Mid device 10, that is, may be the same as the total number of the power amplifier and the low noise amplifier in the radio frequency PA Mid device 10, and in this embodiment, the first switch unit 100 may be the 4P6T switch 130. The four first terminals of the first switching unit 100 are respectively connected to the four low noise amplifiers in one-to-one correspondence, i.e., to the first low noise amplifier 2111, the second low noise amplifier 2112, the third low noise amplifier 2113 and the fourth low noise amplifier 2114. The remaining two first terminals of the first switching unit 100 are connected to the two power amplifiers in a one-to-one correspondence, i.e., to the first power amplifier 2211 and the second power amplifier 2212, respectively. The four second terminals of the first switch unit 100 are respectively connected with the four antenna ports in a one-to-one correspondence manner, i.e., are respectively connected to the first antenna port ANT1, the second antenna port ANT2, the first round port SRS1, and the second round port SRS 2.

It is understood that, in other embodiments, the first switch unit 100 may be configured with other numbers of first terminals and second terminals to implement the reception control of different numbers of first receiving circuits 210. The first switching unit 100 may selectively turn on different first and second terminals to support transmission control and reception control of different radio frequency signals.

The two transceiver modules 200 are configured to support dual-band transceiving of radio frequency signals, that is, one transceiver module is configured to support transceiving of a first radio frequency signal, and the other transceiver module is configured to support frequency band transceiving of a second radio frequency signal. The transceiver module 200 includes two first receiving circuits 210 corresponding to two different transceiving frequency bands, the rf PA Mid device includes four first receiving circuits 210, and output ends of the four first receiving circuits 210 are respectively connected to the four receiving ports in a one-to-one correspondence manner. In this embodiment, the four low noise amplifiers may support amplifying the radio frequency signals transmitted on different frequency bands and different channels, and the processing operations of the four low noise amplifiers are independent of each other. Specifically, the first low noise amplifier 2111 and the second low noise amplifier 2112 are configured to support dual channel reception of a radio frequency signal in the N77 frequency band, and the third low noise amplifier 2113 and the fourth low noise amplifier 2114 are configured to support dual channel reception of a radio frequency signal in the N79 frequency band.

In this embodiment, by integrating the first switch unit 100 and the plurality of transceiver modules 200 in the same device, and setting the transmitting circuit 220 and the plurality of first receiving circuits 210 in the transceiver module 200, the transmitting control of the radio frequency signals of different frequency bands and the receiving control of multiple channels can be realized through the switching function of the first switch unit 100, so that the functions of dual-band transmitting and multiple-channel receiving can be realized without the support of hardware structures such as an external LFEM device (low noise amplifier front-end module) and a switch. Therefore, the present embodiment provides a rf PA Mid device 10 with high integration and low requirement for external hardware structure.

It will further be appreciated that in the prior art, the rf PA Mid device 10 needs to work with LFEM devices, while each external LFEM device needs to occupy approximately 12mm 2 of area. Furthermore, the LFEM device also needs additional power supply and logic control modules to implement its functions, but when a plurality of modules additionally provided are connected to the rf PA Mid device 10 through a PCB (Printed Circuit Board), the number of wires on the PCB is too large, which results in too compact wiring of the PCB, and further increases difficulty and number of layers of wiring, which results in an increase in manufacturing cost of the whole rf transceiving system. In this embodiment, the radio frequency PA Mid device 10 with a higher integration level can effectively reduce the number and density of wiring, and can also reduce the complexity of the process flow during the assembly of the radio frequency transceiver system, thereby further reducing the overall cost of the radio frequency transceiver system applied to the radio frequency PA Mid device 10 of this embodiment.

In this embodiment, the eight low noise amplifiers can support amplifying the radio frequency signals transmitted on different channels in different frequency bands, and the processing operations of the eight low noise amplifiers are independent of each other. Specifically, the first low noise amplifier 2111, the second low noise amplifier 2112, the third low noise amplifier 2113 and the fourth low noise amplifier 2114 are configured to support dual-channel reception of a radio frequency signal of an N77 frequency band, and the fifth low noise amplifier, the sixth low noise amplifier, the seventh low noise amplifier and the eighth low noise amplifier are configured to support dual-channel reception of a radio frequency signal of an N79 frequency band.
