Abstract
There is provided a power amplifier capable of improving harmonics characteristics of an output signal of an amplifier circuit by compensating a phase of the output signal. A power amplifier according to an aspect of the invention may include: an amplification section having a plurality of amplification units each amplifying a radio frequency (RF) signal according to a gain being controlled; a phase correction section performing phase correction by removing harmonic components of respective output signals from the plurality of amplification units of the amplification section; and a coupling section coupling the respective output signals phase-corrected by the phase correction section.
