Abstract
In a radio telephone equipment which includes a portable radiotelephone (100) and a booster (400), an output from the portable radiotelephone (100) whose output level is set according to a level control signal transmitted from a base station is amplified with a preset amplification factor by an automatic gain control circuit (22) provided in the booster (400). As a result, since the amplification factor of the amplifier in the booster and the portable radiotelephone are independently controlled, the booster can be connected to even a portable radiotelephone which is designed without considering that it will be connected to the booster.
