Abstract

PURPOSE:To reduce power consumption and to decrease signal distortion by making a difference between the high and low reference levels of a reception input level greater than that between the high and low levels of a transmission output. CONSTITUTION:A transmission output Ptb from an opposite station (b) is received by a station (a) as a reception input Pra through an antenna 11, a transmitter and receiver 10, and the receiving amplifier 14 of a reception part 13. At this time, the received signal is monitored through a directional coupler 15; when the level of the reception input decreases below a low reference level value P2, the transmission output is increased and when the level increases above a high reference level value P1, the transmission output is decreased. Then, the power switch SW1 of a reflecting amplifier 9 is turned on and off through a control circuit 12 so that a difference between the high and low reference level values of the reception input level is greater than that between the high and low output level of the transmission output level. When the switch SW1 is turned on, a signal has the high output level and is transmitted from the antenna 11.
