摘要： Modulated signals inputted through terminals 11 1 -11 n are converted in frequency into signals of mutually different frequency bands by means of frequency converting means 12 1 -12 n . The converted signals are supplied to a power combining means (16) respectively through variable attenuators 21 1 -21 n , multiplexed and outputted. Part of the multiplexed output is extracted and a level detecting means (23) detects the envelope power level. A control means (24) inputs the level L detected by the detecting means (23). When the level L exceeds the level L s which is k-times (k is about 4 or 5) higher than the average power of the multiplexed signals, the control means (24) attenuates the average power of the modulated signals by a fctor of k/n during the period of about 1/ΔF 0 (sec.) (where ΔF 0 is the band-width frequency of the multiplexed signals) by means of the attenuators 21 1 -21 n .
