<p>Disclosed is a power amplifier, which can lessen distributive and synthetic losses, minimize the size and realize a high effective signal wave thereof. The power amplifier comprises phase converters allocated at front and rear ends of the amplifying elements to include inductors employing an air core coil having a high Q value in a high frequency band, where the phase converter located at the front end of the amplifying elements distributes an input signal to an antiphase signal with the same oscillating width so as to be amplified by the amplifying elements, and the phase converter located at the rear end of the amplifying elements synthesizes and outputs the antiphase signal amplified by the amplifying elements.</p> |
