Abstract :
A new technique for obtaining high RF/LO to IF isolations in microwave mixers is reported. The technique is derived from the concepts of transversal filtering and distributed mixing. An MMIC prototype has been developed which measures only 1.4 mm/spl times/1.3 mm. Over 30 dB of RF/LO to IF isolations have been achieved at X-band and Ku-band.<>
