PURPOSE: A power amplifier is provided to reduce distributive and synthetic losses, minimize the size and realize a high effective signal wave thereof by employing a phase converter, which uses an air core coil having a high Q value as an inductor. CONSTITUTION: A power amplifier comprises phase converters(10,20) allocated at front and rear ends of the amplifying elements(25,26) to include inductors(L1-L8) employing an air coil having a high Q value in a high frequency band, where the phase converter located at the front end of the amplifying elements(25,26) distributes an input signal to an antiphase signal with the same oscillating width so as to be amplified by the amplifying elements(25,26), and the phase converter located at the rear end of the amplifying elements(25,26) synthesizes and outputs the antiphase signal amplified by the amplifying elements(25,26).
