In a feedforward amplifier with a simplified circuit configuration, leakage signals are prevented between output terminals of a pilot oscillator and between input terminals of a detector circuit to remove distorted signals with almost ideal improvement. Each of an output change-over section of the pilot oscillator and an input change-over section of the detector includes a multistage change-over switch or an isolator, the pilot oscillator and the detector being shared between a distortion detecting loop and a distortion removing loop.
