Abstract:
Disclosed herein is a power amplifier insensitive to load impedance changes. According to the present invention, the power amplifier comprises a power amplification circuit which amplifies an input signal, an output matching circuit connected to an output terminal of the power amplification circuit to perform impedance matching between the power amplification circuit and an antenna load, and a 4-port coupler connected between the output matching circuit and the antenna load.
