Abstract :
Multilayer dual mode HTS filter is the smallest known high-performance filter structure, occupying less than 1% in volume as compared to the state-of-the-art dielectric resonator counterpart. It can also be manufactured in form of a flat-pack surface mounted flip-chip module suitable for integration with other components in a cryogenic payload. In this presentation, we report recent advances made in the areas of design and packaging of this vertically stacked multilayer filter. A C-band 4-pole quasi-elliptical bandpass filter in its smallest configuration, implemented using either gold (Au) or YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// (YBCO) thin film dual mode patch resonators on magnesium oxide (MgO) substrates, is presented.
