Abstract
Systems and methods for enhancing the linearity of a modulator by filtering a set of frequency components from the modulator output to develop a modulator feedback signal. In a preferred embodiment of the invention, a diplexer separates the output of a balanced modulator into a first frequency spectrum and a second frequency spectrum. The first frequency spectrum contains the modulated output signal, and the second frequency spectrum contains the modulator feedback signal which is combined with the modulating signal to enhance the linearity of the modulator.
