Abstract
An isolator eliminator for a linear transmitter receives a plurality of digital samples of an information signal and a drive signal sampled from a feedback loop at periodic time intervals and, responsive to processing the digital samples, provides high accuracy phase and level correction signals to the feedback loop. The phase and level correction signals maintain stable, linear operation of the feedback loop and limit splatter. In a preferred embodiment, the isolator eliminator includes a digital signal processor such that multiple communication protocols may be accommodated by changing software code executed by the processor.
