RF communication systems with interference cancellation for coexistence are provided herein. In certain embodiments, a method of interference cancellation includes filtering a radio frequency (RF) transmit signal to generate a first RF feedback signal using a first filter of a front end system, filtering the RF transmit signal to generate a second RF feedback signal using a second filter of the front end system, processing the first RF feedback signal to generate a first digital interference cancellation signal using a first feedback receiver, processing the second RF feedback signal to generate a second digital interference cancellation signal using a second feedback receiver, and compensating an RF receive signal for interference based on the first digital interference cancellation signal and the second digital interference cancellation signal using a receiver.

Mixed signal low noise interference cancellation

Antenna-plexers for interference cancellation are provided herein. In certain embodiments, a wireless device includes an antenna, an antenna-plexer coupled to the antenna and configured to generate a feedback signal, a transmitter configured to transmit a transmit signal to the antenna by way of the antenna-plexer, a receiver configured to process a receive signal, and a feedback receiver configured to process the feedback signal from the antenna-plexer to provide compensation to the receive signal.

Antenna-plexer for interference cancellation

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 circuit, a receiver that processes a receive signal from a second front end circuit, and a feedback receiver that processes a feedback signal from the first front end circuit to generate a digital interference cancellation signal that compensates the receiver for interference arising from the transmitter.
