<p>In a portable wireless telephone comprising a portable wireless telephone set (100) and a booster (400), the output of the portable wireless telephone set (100), the output level of which is set in accordance with a level control signal transmitted from a base station, is amplified to a predetermined level by an automatic gain control circuit (22) disposed inside the booster (400). As a result, since the amplification factor of the amplifier inside each of the portable wireless telephone set and the booster can be independently controlled, the booster can be connected to a portable wireless telephone designed for operation without a booster.</p> |
