1. A radio-frequency Power Amplifier Modules including Duplexers (PA Mid) device, having a coupling output port, a coupling input port, and an antenna port configured to connect to an antenna, the radio-frequency PA Mid device comprising:
a transceiving circuit connected to the antenna port and configured to support transceiving control of a radio-frequency signal;
a coupling unit comprising:
an input port coupled to the transceiving circuit;
an output port coupled to the antenna port;
a first coupling port configured to couple the radio-frequency signal and output a forward coupled signal; and
a second coupling port configured to couple a reflected signal of the radio-frequency signal and output a reverse coupled signal; and
a coupling switch connected to the first coupling port, the second coupling port, the coupling output port, and the coupling input port, wherein the coupling switch is configured to selectively output, via the coupling output port, the forward coupled signal, the reverse coupled signal, or an external coupled signal received via the coupling input port.
