Abstract
A power amplifier of the present invention includes a distributor () for distributing an input signal; an anti-phase third-order intermodulation distortion generation circuit () for, upon receiving the input signal that was distributed by the distributor, generating third-order intermodulation distortion for which the phase difference is anti-phase with respect to each of two main signals of different frequencies and supplying the two main signals and the third-order intermodulation distortion; a first amplifier () for amplifying the signal received from the anti-phase third-order intermodulation distortion generation circuit and supplying the result; a second amplifier () for amplifying the input signal that was distributed by the distributor and supplying the result; and a synthesizer () for combining the output signal of the first amplifier and the output signal of the second amplifier.
