Abstract

A power amplifier circuit includes a power amplifier and an output matching circuit that includes a first capacitor and a switch unit. The first capacitor has a first end electrically connected to an output end of the power amplifier. The switch unit includes a first input terminal, a second input terminal, a first output terminal, and a second output terminal. The switch unit causes the first input terminal to be connected to the first output terminal and causes the second input terminal to be connected to the second output terminal in a first operation mode of the power amplifier, and causes the first input terminal to be connected to the second output terminal and causes the second input terminal to be open or to be connected to the first output terminal in a second operation mode of the power amplifier.
