Abstract
A method and an apparatus for amplifying power in a communication system is disclosed that includes a detection module which detects a power level of a predetermined signal selected from among an input signal and an output signal of a power amplifier and then transmits an operation mode control signal for the power amplifier; a gate bias controller which controls a gate bias of the power amplifier in accordance with the detected power level; and a power amplifier which operates as class B or class A in accordance with control by the gate bias controller to generate a pre-distortion component, offsets a distortion component generated during amplification of the predetermined signal by synthesizing the pre-distortion component with the distortion component, and outputs only the predetermined signal without a distortion component.
