Abstract
A high efficiency multiple power level amplifier circuit for reducing power consumption during low power operations. A plurality of power amplifier stages are cascaded to provide multiple levels of amplification. At least one power amplification stage includes a signal switching network to allow one or any combination of power amplifiers to be switched out when lower power operations are desired. The switched out power amplifiers are biased such that substantially no current is drawn from the power source.
