ABSTRACT:
An improved feedforward amplifier capable of enhancing accuracy of extraction of an error signal corresponding to a distortion component while preventing outflow of an pilot signal. A switch is disposed between a pilot signal oscillator and a third power combiner for superimposing the pilot signal on an output signal from a main amplifier, and third control means is connected with the switch so that the switch is opened at the time of error signal extraction and closed at the time of error signal elimination.
