Abstract
An amplification device includes a first filter configured to pass a predetermined frequency component of a first digital signal phase-modulated with a constant amplitude; a first distortion compensator configured to compensate the signal output from the first filter in advance for distortion occurring in an amplified signal, based on a first distortion compensation coefficient dependent on an amplitude of the signal output from the first filter; a first converter configured to convert the signal compensated by the first distortion compensator into a first analog signal; and a first amplifier configured to amplify the first analog signal.
