Abstract
Successful development of High Temperature Superconducting (HTS) tunable devices such as multipole band pass filters and demonstration of their high-Q performance will lead to significant enhancements in several military and commercial communications systems The primary objective of the present SBIR program is to develop magnetically tunable HTS filter technology, integrating the superconducting properties of the HTS prototype YBa2Cu307 (YBCo) with the ferrimagnetic properties of the Yttrium Iron Garnet layers on Gadolinium Gallium Garnet (YIG/GGG) substrates. Combining our expertise in device design and materials engineering, the Neocera-University of Maryland team proposes a novel device configuration by which the bandwidth of the filter is expected to remain fixed retaining the high-Q performance, as the filter's central frequency is tuned by an applied magnetic field. In this effort, HTS filters will be developed on YIG/GGG substrates and their frequency agile properties will be evaluated. Phase I effort will form the basis for fabricating frequency adaptive multipole HTS filters in a subsequent Phase II program.
