Abstract
A power amplifier circuit includes a first amplifier that amplifies an input signal and outputs a first amplified signal, a second amplifier that is disposed subsequent to the first amplifier and that amplifies the first amplified signal and outputs a second amplified signal, and a clamp circuit that is disposed between ground and a signal line extending between the first amplifier and the second amplifier and that suppresses an amplitude of the first amplified signal.
