According to one side of the present invention, the broad band high linear power amplifier comprises: a plurality of predistorting unit that linearize each of digital signals in a plurality of bands; a synthesizing unit that synthesizes an output signal of the predistorers; a single amplifying unit that amplifies a signal outputted from the synthesizer; a distributing unit that separates the plurality of signals by band from the output signal of the amplifying unit; a plurality of reverse-reward attenuating unit that attenuate the separated plurality of signal by band; and a feedback gyro that performs feedback of the attenuated plurality of signal by band to the predistorting unit of the corresponding band from among the plurality of predistorting units. |
