Abstract
There is provided a power amplifier and an integrated circuit including the power amplifier. The power amplifier includes a first amplifier configured to amplify a first signal; a phase shifter configured to invert the first signal; and a harmonic sinker connected between an output terminal of the phase shifter and an output terminal of the first amplifier, configured to amplify an output signal of the phase shifter, and configured to have a conduction angle narrower than a conduction angle of the first amplifier.
