Abstract

PURPOSE:To obtain a parallel operation system by which AM modulation electric power can be compounded so as to be well-balanced, and also a redundant operation can be executed. CONSTITUTION:The output of the carrier oscillator 22 energizes in phase the electric power amplifiers to be modulated 251, 252 through the energizing circuits 231, 232. A series modulation amplifier 241 is inserted between the electric power source 261 and the electric power source terminal of the electric power amplifier to be modulated 251, and in the same way, a series modulation amplifier 242 is inserted between the electric power source 262 and the electric power source terminal of the electric power amplifier to be modulated 252, too. And, the outputs of the electric power amplifiers to be modulated 251, 252 are compounded by the compounding circuit 28. On the other hand, the outputs from the modulators 241 and 242 are provided to the input terminal of the differential amplifier 30, and the output of said amplifier 30 is fed back to the modulators 242 and 241, respectively. Accordingly, the outputs from 251 and 252 are always balanced equally and are provided to said compounding circuit 28.
