Claim Text:
1. A LINC power amplifier, comprising: at least three power amplifiers; a first circuit to select, based on an amplitude of an input signal, at least two partial signals used for combination among the at least three partial signals to be inputted to the at least three power amplifiers, and to determine, based on the amplitude and a phase of the input signal, an amplitude and a phase of each of the at least two partial signals so that an efficiency of the LINC power amplifier is increased; a second circuit configured to receive the at least two partial signals each having the amplitude and the phase that are determined to correspond to the power amplifiers among the at least three power; and a combiner to combine signals obtained by amplification of the at least two partial signals at the corresponding power amplifiers.
