Abstract
An amplifying device 1 of the present invention performs distortion compensation on distortion appearing in input-output characteristics of an amplifier 4 based on an input signal and an output signal of the amplifier 4, and includes a predistorter 23 that obtains the input signal and the output signal and performs distortion compensation of the amplifier; an ACLR calculation unit 25 that detects the distortion level of the distortion of the amplifier 4; and an adjustment unit 26 that adjusts the power of the input signal in accordance with the distortion level.
