For example, the first switching device 210 may select to turn on the rf path between the second transceiver module 120 and the antenna port ANT3, and simultaneously turn on the rf path between the third transceiver module 130 and the antenna port AUX 1.

It is understood that the first switching device 210 may implement two first terminals and a plurality of second terminals through connection of a plurality of different switches, and the application does not specifically limit the internal structure of the first switching device 210. For example, fig. 5 shows a 2P3T switch and a 3P4T switch that together form a first switching device 210 having two first terminals and five second terminals.

It can be understood that, in the prior art, if it is necessary to implement a radio frequency transceiving system that performs transceiving in N41, N77, and N79 frequency bands, it is usually necessary to connect a plug-in radio frequency PA Mid device 10 in N41 frequency band, and in this embodiment, by integrating the transceiving modules 100 in N41, N77, and N79 frequency bands into the same radio frequency PA Mid device 10, the radio frequency PA Mid device 10 in N41 single frequency band can be removed, so as to approximately save the area of 20mm ^2 in the radio frequency transceiving system, and further to make up physical space for performance optimization of other modules. Moreover, the three-band rf PA Mid device 10 can simplify power supply layout and logic control routing, which is more favorable for signal integrity, reduces mutual interference between signals, and simultaneously reduces the number and density of Printed Circuit Board (PCB) wirings, and can also reduce the complexity of the process flow during assembly of the rf transceiver system, thereby further reducing the overall cost of the rf transceiver system to which the rf PA Mid device 10 of this embodiment is applied.
