Design and Development of a Narrow Band Dielectric Resonator Filter at Ku Band
This paper describes the design and development of very Narrow Bandwidth Ku-Band Filter required for Frequency Generator. It will provide desired in-band response in very narrow bandwidth 0.05 % and sharp rejection at specific frequencies > 48dBc. Quasi-Elliptic Filter function with two out-of-band transmission zeros used to achieve required near band rejection specifications. Cascaded-quadruplet topology is used to generate near-band transmission zeros. Dielectric resonator technology used to develop the filter. DR Filter structures is modelled, fabricated, and tested. The Design has been validated with the test performance.
