Abstract: A circulator based transceiver sharing a common antenna between a receive signal path and a transmit signal path is disclosed. Techniques to reduce coupled transmit signals and coupled transmit noise in a receive signal path, implemented in a variety of embodiments is disclosed allowing elimination of a diplexer, simplification of circulator design and reduction of transceiver cost. The transceiver includes means to generate and couple a correction signal into the receive signal path to attenuate coupled transmit signal in the receive path. Furthermore, the transceiver includes echo cancellation techniques to attenuate transmit noise in the receive signal path. Methods to utilize the transceiver to attenuate coupled transmit signal and transmit noise may improve transceiver efficiency, for example, in demodulation techniques and processing of data signal.
