Filed: 1984-04-19
Abstract: PURPOSE:To reduce the generation of heat of a portable device by minimizing the transmission output of the portable device by the detected signal obtained when unifying the portable device and an output amilifier at a radio communication equipment. CONSTITUTION:A radio communication equipment is provided with a portable radio communication equipment 11 and a transmission output amplifier 2. The transmission output of the equipment 11 is increased. In such a case, both the equipment 11 and the amplifier 2 are unified. A connection detecting part 16 is added to the equipment 11 to detect that the equipment 11 and the amplifier 2 are unified. A transmission power control circuit 100 is controlled by the output of the part 16. Thus it is possible to change the reference voltage of the circuit 100 and to reduce the transmission output of the equipment 11 down to the minimum input level required by the amplifier 2 when the equipment 11 is connected to the amplifier 2. This can minimize the generation of heat of the equipment 11.
