Notch Filters for Interference Mitigation in SATCOM Systems

This project focuses on the development of compact tunable notch filters for interference mitigation in 3GPP satellite arrays. The filters will be integrated into a commercial 3GPP SATCOM array system and flight tested to demonstrate enhanced systemresiliency in the presence of self-generated and external RF interference. The Phase II Base effort will focus on the integration of the notch filters and an appropriate controller, and flight tested on a 3GPP SATCOM system in the UHF spectrum. A high-speed controller will also be developed and bench-top tested for sub-microsecond tuning. The Option I effort will focus on increasing the maturity level of the filters controlled by high-speed tuning through batch testing as well as increasing the frequency coverage and integration level with the targeted SATCOM system. Finally, the Option II effort will leverage the results of
