Abstract
A power amplifier according to examples includes an amplifying circuit configured to amplify an input signal, a feedback circuit configured to feedback the amplified signal to the amplifying unit, and a feedback controlling circuit configured to control a power of the fed-back signal based on a power of the input signal. The feedback controlling unit performs controlling so that the power of the fed-back signal is increased as the power of the input signal is increased.
