Abstract
PURPOSE:To eliminate the need for a power source only for a switch, a logic circuit for sequence control, and standby route terminating dummy load of the switch by switching and using the power source of a standby power amplifier for the switch in common. CONSTITUTION:If trouble occurs in an existing power amplifier 3, an alarm signal is sent to a transmission system control board 9. The logic circuit in the transmission system control board 9 operates a switch 10 by a power source 10 in accordance with this signal to switch the transmission route to the standby system. That is, the output of a standby power amplifier 5 is connected to an antenna 11. When a response signal of switching completion is sent from the switch 10, the transmission system control board 9 receives this signal and controls a switch 8 to connect the power source 6 to the standby power amplifier 5. Thus, the sequence control is unnecessary, and the logic circuit is simplified, and standby route terminating large-capacity terminator dummy load of the switch is unnecessary.
