PURPOSE:To enable the prevention of momentary interruption of output signal, by all the systems in parallel which are controlled in the same phase and output with synthesis. CONSTITUTION:The reception signal from the signal input terminals IN1, IN2 is fed to No.1 reception system (reception conversion section RX1 and local oscillator LO1) and No.2 reception system (RX2, LO2) and then fed to the phase synthesis section PSC after conversion, and the local oscillator LO2 is controlled so that the phase difference is zero and fed to the transmission system SER-2 with synthesis. When this signal is received at the transmission conversion sections TX1, TX2, it is converted at the local oscillation signal from the local oscillation synthesis section LOC and fed to the circulator synthesis section CIR, and synthesized at a plurality of circulators provided in it into output. In the local oscillation and synthesis section LOC, the local oscillators LO3, LO4 in parallel operation receives specified phase control, and the output is output with synthesis. |
