Abstract
Systems and methods are provided for amplifying a composite input signal, comprising a drive signal and an envelope signal, at a power amplifier. A secondary modulation, representing a portion of the composite input signal falling outside of a frequency band associated with the envelope signal, is produced for the drive signal. The secondary modulation is applied to the drive signal. The drive signal is amplified at the power amplifier to produce an amplified signal. At least a portion of the envelope signal is employed to drive a supply terminal of the power amplifier.
