Power- conserving drive-modulation method for envelope-elimination-and-restoration (EER) transmitters
TL;DR: In this paper, a method and a circuit for high-efficiency linear RF-power amplification over a wide range of amplitudes from zero to peak output includes a final RF power amplifier operating at or near saturation, an RF driver amplifier, a high-level amplitude modulator for the final amplifier, and a means for determining the supply-voltage input to the final amplifiers and for controlling the amplitude of the drive.
