Abstract

A system for communicating information includes a variable gain amplifier (VGA) responsive to an input signal and a gain control signal for controlling a gain of the VGA. The system also includes a power amplifier responsive to the VGA. An output power level of the power amplifier is compared to a predetermined reference value to generate the gain control signal. The gain control signal is offset by a gain offset value. To change the output power level of the power amplifier from a first output power level to a second output power level, a first predetermined reference value and a first gain offset value associated with the first output power level are changed substantially concurrently to a second predetermined reference value and a second gain offset value, respectively, associated with the second output power level.
