Title:
PHASED ARRAY ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/167145
Kind Code:
A1
Abstract:
According to the present invention, synthesizers (32, 24) that synthesize feedback signals output from multiple antenna modules (4) are provided and a distortion compensation signal output unit (15) obtains, from the difference between the feedback signals synthesized by the synthesizers (32, 24) and a baseband signal output from a modulator (12), a distortion compensation coefficient that provides distortion characteristics that are the reverse of the distortion characteristics of a signal emitted from a phased array antenna to the baseband signal and outputs a predistortion signal that indicates the distortion compensation coefficient to a PD unit (13).
