Abstract :
The application of epitaxial YIG resonators in a tunable notch filter design with a center frequency of 9 GHz is reported. Tuning from 8 to 19 GHz was accomplished via a miniature electromagnet with a volume of about 1 cm/sup 3/. This volume gives the filter application in phased arrays of simultaneous transmit/receive antenna modules.<>
