Signal extraction circuit and distortion-compensated amplifier incorporating the same

Image Number 14 for United States Patent #7456688.

To cancel a reflected wave reflected from a connecting portion (22) and leaking into a feedback signal when a non-matched component is connected, the reflected wave is extracted by a circulator (30) and its phase and amplitude are adjusted by a vector adjusting circuit (32), and then the thus adjusted reflected wave is vector-summed with the feedback signal in a vector sum circuit (34).
