Abstract

A power amplifier circuit includes: an amplifier that amplifies an input signal; and a resonant circuit that is connected to an output terminal of the amplifier and that attenuates a harmonic wave of an amplified signal obtained by amplifying the input signal. The resonant circuit includes an inductor disposed between the amplifier and a ground, a capacitive element disposed between the amplifier and the ground and connected in series to the inductor, an inductor connected in parallel to the inductor, a switch connected in series to the inductor, and a switch that is connected in parallel to the switch and that is of an element size common to an element size of the switch.
