Abstract
A circuit that increases the efficiency of a radio frequency mobile telephone unit is disclosed. When the signal strength between the base station and the mobile unit is below a predetermined signal strength level, the power amplifier is turned on and the transmitter circuit of the mobile unit fully amplifies the RF signal. However, when the signal strength between the mobile telephone unit and the base station is above a predetermined signal strength level, the power amplifier is deactivated and bypassed from the transmitter circuitry, thereby conserving the battery power of the mobile unit.
