Amplification apparatus

Abstract

An amplification apparatus includes a separator configured to separate an input signal into a first signal and a second signal, a first and second amplifiers amplify the first and second signal, a storage, and a processor coupled to the storage and configured to adjust a phase of the second signal on the basis of a first phase value corresponding to a power value of the input signal or a second phase value set within a period in which the first phase value is updated, calculate a power value of an output signal that is synthesis of an output of the first amplifier and an output of the second amplifier, and update the first phase value to the second phase value after the change of the power value of the calculated output signal when the first phase value is the power value of the input signal.
