Abstract
Synthesizers (32, 24) for synthesizing feedback signals output from a plurality of antenna modules (4) are provided. A distortion compensation signal output unit (15) derives, from a difference between a feedback signal synthesized by the synthesizers (32, 24) and a base band signal output from a modulation unit (12), a distortion compensation coefficient that provides, to the base band signal, distortion characteristics opposite to distortion characteristics of a signal radiated from the phased array antenna and outputs a predistortion signal representing the distortion compensation coefficient to a PD unit (13).
