Wireless transceiver with circulator and active cancellation and methods for use therewith

A wireless transceiver comprising:

• a transmit path configured to generate a radio frequency (RF) transmit signal for transmission via an antenna that includes a programmable antenna tuning unit, the transmit path generating a feedforward signal having at least one adjustable phase;
• a receive path configured to receive an RF receive signal via the antenna and the feedforward signal;
• a circulator-based duplexer including a circulator configured to couple the transmit signal from the transmit path to the antenna and to couple the RF receive signal from the antenna to the receive path;
• and
• a controller configured to process feedback from the receive path, to control the at least one adjustable phase to cancel portions of the transmit signal on the receive path, to selectively deactivate the feedforward signal based on mode control data and further to control the programmable antenna tuning unit to compensate for impedance of the antenna.

A method comprising:

• generating a radio frequency (RF) transmit signal for transmission via an antenna;
• generating a feedforward signal having at least one adjustable phase, wherein the generation of the feedforward signal is selectively deactivated based on mode control data;
• receiving an RF receive signal from the antenna and the feedforward signal via a receive path;
• isolating the transmit signal from the receive path via a circulator configured to couple the transmit signal to the antenna and to couple the RF receive signal from the antenna to the receive path;
• and
• processing feedback from the receive path to control the at least one adjustable phase to cancel portions of the transmit signal on the receive path.
