The compensation range of feed-forward amplifiers is expanded. The peak value of the input or output of an auxiliary amplifier 15 is detected with a peak power measuring instrument 24, and the characteristic of a distortion detecting loop 100 is controlled with a vector adjuster 3 and a control circuit 9 so as to minimize this peak value. By controlling the characteristic of the distortion detecting loop by detecting the peak value, the range of linearity compensation is expanded compared with conventional control based on the average level.
