Abstract
A power amplifier module includes a first power amplifier that amplifies an input signal and outputs a first transmission signal; a first switch circuit that receives input of the first transmission signal and performs switching to, of a plurality of signal paths, a signal path through which the first transmission signal passes; and a second switch circuit that receives input of the first transmission signal output from the first switch circuit through the signal path to which the first switch circuit has performed switching and switches between signal paths to an antenna terminal. The second switch circuit includes a power supply circuit that supplies a reference voltage to the first switch circuit and the second switch circuit.
