Abstract
A drain modulator circuit for operation with a radio frequency (RF) amplifier, includes a pair of AC signal sources each of the AC signal sources having an output at which an AC signal is provided. The drain modulator circuit further includes a pair of tapped delay elements, each of which is configured to receive an AC signal from a respective one of the AC signal sources and a control element coupled to provide one or more control signals to the pair of tapped delay elements such that the tapped delay elements provide a selected instantaneous differential voltage to the RF amplifier.
