COMPACT RAPIDLY ADJUSTING FILTER Navy SBIR FY2012.2 Sol No.: Navy SBIR FY2012.2 Topic No.: N122-127 Topic Title: COMPACT RAPIDLY ADJUSTING FILTER Proposal No.: N122-127-0773 Firm: H6 Systems Inc. 55 Lake Street Nashua, New Hampshire 03060 Contact: Michael Hunter Phone: (603) 880-4190 Web Site: h6systems.com Abstract: Coupled cavity TWTs offer a near solution to the peak/average power test requirements of MIL-STD-464 and MIL-HDBK-235. They fall short by their inadvertent generation of low-power (<1W) broadband noise which can extend beyond the TWT's intended broadcast band and can interfere with peripheral circuits such as GPS. H6 Systems proposes to develop a Compact Rapidly Adjustable Filter (CRAF) solution to the broadband noise problem that will allow TWTs to be used as sources for susceptibility testing. Both a switchable design (easily switching between frequencies) and a tunable design (controller-based motor-tuned filter) will be investigated. A Compact Rapidly Adjusting Filter will allow greater coverage of the MIL-STD-464 specification than is now possible. Government test centers such as Dahlgren, Redstone, Patuxent River, and White Sands will have use for multiple Compact Rapidly Adjustable Filters to expand their test capability. Benefits: A Compact Rapidly Adjustable Filter (CRAF) solution to the TWT broadband noise problem will allow greater coverage of the MIL-STD-464 specification. The proposed Phase I work plan will show the feasibility of CRAF filter design. Government test centers such as Dahlgren, Redstone Arsenal, Patuxent River and White Sands will have use for multiple Compact Rapdily Adjustable Filters (CRAFs) to expand their test capability. Return
