Abstract
System and method for signal modulation. In one embodiment, a circuit includes a channel for carrying an analog RF signal, a phase offset circuit on the channel, and configured to receive a phase code for modifying the analog RF signal to produce a modified RF signal, and a feedforward cancellation path coupled in parallel to the phase offset circuit for canceling a portion of the modified analog signal.
