Abstract
An amplifying apparatus includes an amplifying unit that includes multiple amplifiers coupled in parallel; a measuring unit that measures in a predetermined period, frequency distribution of any one among instantaneous power and instantaneous voltage of a signal amplified by the amplifying unit; a calculating unit that calculates for multiple candidate values of a predetermined parameter of the amplifying unit, efficiency of amplification that is performed by the amplifying unit and based on the frequency distribution; and a controller that controls the predetermined parameter, based on the efficiency calculated for the candidate values by the calculating unit.
