Abstract

A power amplifier circuit includes an input that receives a first input signal having a first phase and a second input signal having a second phase, a first transistor that includes a source that is supplied with a first voltage, and a gate that receives the first input signal, a second transistor that includes a source that is supplied with the first voltage, and a gate that receives the second input signal, a first neutralizing circuit that neutralizes a parasitic element, a second neutralizing circuit that neutralizes a parasitic element, N third transistors, N being an integer equal to or higher that 1, N fourth transistors, and an output that is connected between a drain of the N-th third transistor and a drain of the N-th fourth transistor and outputs a first output signal having a third phase and a second output signal having a fourth phase.
