Abstract
A power amplifier may include an amplifying unit configured to amplify an input signal, an impedance varying unit connected between the amplifying unit and an output port that is for outputting an amplified signal of the input signal, and a controller configured to output a first control signal based on a level of power of the amplified input signal of the amplifying unit to control a varying of impedance of the impedance varying unit.
