Abstract :
A compact, broadband linearizer has been developed at Space Systems Loral for Ka-band communication satellite (20 GHz down link). The pre-distortion type linearizer is capable of providing up to 10 dB gain compensation and 80 degree phase compensation, and is suitable for a broadband communication satellite.
