Abstract
Radio frequency (RF) communication systems with interference cancellation for coexistence are provided herein. In certain embodiments, an RF communication system includes a transmitter that transmits a transmit signal through a first front end system, a receiver that processes a receive signal from a second front end system, and an interference cancellation circuit that generates an interference cancellation signal that compensates the receiver for interference arising from the transmitter. The interference cancellation circuit includes a filter for filtering the transmit signal, a controllable phase circuit for adjusting a phase of the interference cancellation signal, and a controllable gain circuit for adjusting a gain of the interference cancellation signal.
