PROBLEM TO BE SOLVED: To miniaturize a circuit scale by unnecessitating a sub-amplifier and a delaying device having large saturation power in a conventional distortion compensating amplifier of a feedforward circuit. SOLUTION: The distortion compensating amplifier is provided with a distributor for distributing an input signal, a first amplifier for amplifying a first distribution signal of the distributor, a second amplifier for amplifying a second distribution signal of the distributor and a coupler for synthesizing amplifying signals of the first and second amplifiers to be an opposite phase to each other to reduce distortion components included in the amplifying signal of the fist amplifier.
