Abstract

A power amplifier includes a first amplifier unit, a second amplifier unit, a first switching element, a second switching element and a third switching element. Each of the amplifier units includes a power supply terminal, a ground terminal, an input terminal, and an output terminal, and amplifies a signal received at the input terminal according to a voltage between the power supply terminal and the ground terminal, and outputs the signal from the output terminal. The first switching element is connected between the ground terminal of the first amplifier unit and the power supply terminal of the second amplifier unit. The second switching element is connected between the ground terminal of the first amplifier unit and a first reference voltage terminal. The third switching element is connected between the power supply terminal of the second amplifier unit and a second reference voltage terminal.
