Abstract
A transmitter-receiver isolation circuit includes a transmitter port to receive a transmit signal, an antenna port for coupling to an antenna, and a receiver port to receive a receive signal. The circuit further includes: a first signal path between the transmitter and antenna ports configured to impart a first phase shift to a first transmit portion of the transmit signal; a second signal path between the transmitter and antenna ports configured to impart approximately the first phase shift to a second transmit portion of the transmit signal; a first leakage path between the transmitter and receiver ports configured to impart a second phase shift to a first leakage portion of the transmit signal; a second leakage path between the transmitter and receiver ports configured to impart to a second leakage portion of the transmit signal a third phase shift that is approximately opposite to the second phase shift.
