The frequency characteristic of the variable frequency characteristic amplifier FCA is controlled in accordance with a comparison signal between the output signal DLO of the low band-pass amplitude detector DL and the output signal DHO of a band-pass amplitude detector DH, namely, a frequency characteristic control signal FC. Thus, the peak of a reception signal is suppressed and the waveform distortion of the output signal WAO* is suppressed.
