Abstract
A communications device includes an amplifier module configured to amplify a signal. The amplifier module includes a parallel arrangement of amplifiers each designed to operate with increased efficiency for different power level ranges. A controllable switch selectively interconnects the power amplifiers. A controller in communication with the controllable switch selectively interconnects the power amplifiers to increase the efficiency of the amplifier module.
