Abstract

There is disclosed, for use in a wireless communication system comprising at least one base station operable to communicate with a plurality of mobile units, a power controller for controlling a power consumption of a linear power amplifier in the base station. The power controller comprises: 1) a first power monitor for determining an RF output power level of the linear power amplifier; 2) a second power monitor for determining a primary power level consumed by the linear power amplifier; and 3) a processing circuit operable to determine an actual power ratio of the primary power level and the RF output power level and to adjust the primary power level to maintain the actual power ratio at approximately a selected target power ratio.
