Abstract
A power amplifier circuit includes a power splitter, a first amplifier, a second amplifier, a third amplifier, a fourth amplifier, a first bias circuit, a first line connecting the first bias circuit and the first amplifier, and a second line connecting the first bias circuit and the third amplifier on the same semiconductor substrate, in which the first line and the second line are formed such that a voltage drop amount of the first bias voltage between the first bias circuit and the first amplifier is substantially equal to a voltage drop amount of the first bias voltage between the first bias circuit and the third amplifier.
