High-Q Filters for GPS and SATCOM Resiliency

This project focuses on the development of high-Q tunable bandpass filters based upon magnetically tuned thin film YIG resonators. Both printed circuit board integrated and all thin film-based devices will be developed.  The filters will be integrated into GPS and SATCOM systems to demonstrate system resiliency in the presence of RF interference. The Phase II Base effort will focus on the deposition and characterization of the thin films using pulsed laser deposition. After material characterization, tunable resonators will be fabricated and characterized. The last portion the base effort will then focus on the design, fabrication, and analysis of low loss filters for GPS applications. The Option I effort will extend the technology under development for SATCOM applications.  Finally, the Option II effort will leverage the results of the previous phases and will focus on integration and testing of the filters in relevant GPS and SATCOM systems.
