发明名称 AMPLIFICATION DEVICE AND AMPLIFICATION METHOD
摘要 PROBLEM TO BE SOLVED: To provide an amplification device that suppresses degradation of an output signal.SOLUTION: The amplification device having a first conversion section for converting a first digital signal that is a constant amplitude phase-modulated signal to an analog signal, and a first amplification section for amplifying the converted analog signal comprises: a first filter for passing a predetermined frequency component of the first digital signal; and a first distortion compensation section for performing distortion compensation which compensates an output of the first filter beforehand for a distortion caused in an output of the first amplification section on the basis of a first distortion compensation coefficient dependent on the amplitude of the output of the first filter, and feeding the distortion-compensated signal to the first conversion section.
