In a radio communication system such as a cellular telephone system having battery powered mobile stations which receive radio frequency signals, an amplifier in the receiver of the mobile station is operated in a plurality of different modes in order to reduce power consumption. The modes of the amplifier depend upon the strength of the incoming signal and whether the transmitter is transmitting. The receiver is also periodically disconnected from the battery in order to further reduce power consumption. |
