Tunable Bandstop Filters for Suppression of Co-site Interference and Jamming Sources

This project will develop tunable notch filter for the mitigation of co-site interference and jamming sources. The novel filter technology explored in the Phase I program has displayed excellent potential to provide wide tuning capability, low out-of-band insertion losses, deep notch depths, compact form factors and low power consumption. Furthermore, by using novel MEMS tuning membranes, high filter tuning speeds will be achieved. The project will also develop automatic feedback and control hardware and firmware to facilitate the integration and testing of the filters in relevant Navy systems. The filters developed under this program will operate in the L to Ku Bands and will be capable of adjusting their center frequencies, notch depths and stopband bandwidths. A graphical user interface will also provide the end user the ability to independently evaluate and test the filters for specific applications.
