PROBLEM TO BE SOLVED: To provide a radio frequency electrical signal generator which sends at least two discrete signals of different frequencies as signals sent from different primary sources and amplified by a predetermined gain. SOLUTION: This apparatus includes, in addition to the primary sources 2, a combining circuit 3 for combining signals sent from the primary sources 2, a single channel power amplifier 4, and a multichannel selection routing device 5 having a parallel structure. Each channel of the multichannel selection routing device 5 includes a stop circuit 6 for supplying an amplification signal S by a characteristic frequency F of one primary source 2 at an output and adjusting to pass one of various characteristic frequencies F of various primary sources 2, an impedance-matching circuit 7, and a rejection circuit 8 for rejecting frequencies other than the frequency passed by the stop circuit 6 of the channel.
