Abstract
Provided is a radio-frequency Power Amplifier Modules including Duplexers (PA Mid) device. The radio-frequency PA Mid device has a coupling output port (CPLOUT), a coupling input port (CPLIN), and an antenna port (ANT). The radio-frequency PA Mid device includes: a transceiving circuit () configured to support transceiving control of a radio-frequency signal; a coupling unit () including an input port (a), an output port (b), a first coupling port (c) configured to couple the radio-frequency signal and output a forward coupled signal, and a second coupling port (d) configured to couple a reflected signal of the radio-frequency signal and output a reverse coupled signal; and a coupling switch () configured to selectively output, via the coupling output port (CPLOUT), the forward coupled signal, the reverse coupled signal, or an external coupled signal received via the coupling input port (CPLIN).
