Summary:PROBLEM TO BE SOLVED: To provide an amplification device capable of suppressing distortion appearing in the input/output characteristics of an amplifier even when distortion caused by a temperature change or deterioration with the lapse of time occurs in the input/output characteristics of the amplifier. SOLUTION: The amplification device 1 for performing distortion compensation of distortion appearing in the input/output characteristics of the amplifier 4 based on an input signal and an output signal of the amplifier 4 includes: a distortion compensation unit 23 for acquiring the input signal and the output signal and performing the distortion compensation of the amplifier 4; an ACLR calculation unit 25 for detecting a distortion level of the distortion in the amplifier 4; and an adjustment unit 26 for adjusting power of the input signal according to the distortion level.
