“…A number of articles on theory and design of three-port circulator can be found in the literature. The emphasis is on performance improvement in terms of insertion loss [15][16][17], wide band operation [20,22,28,29], temperature stabilization [29,30], isolation bandwidth [15,16,23], miniaturization [28,[30][31][32], isolation [17,24] and high power operation [19,21,26,30]. Isolation performance is critical in some radar systems.…”

A circulator is needed in a C-band airborne synthetic aperture radar system which employs single antenna configuration. The circulator provides full-duplex capability to transmit highpower RF signal and receive the echo signal via the same antenna simultaneously. Commercially available circulators with moderate isolation are inadequate for this application. An innovative Cancellation Network (CN) has been designed to enhance the performance of the conventional circulator. This paper highlights the conceptual design and measurement results of the CN. An improvement of more than 27 dB has been achieved.
