COMPACT WIDEBAND TUNABLE FILTERS
SBIR Opportunity Analysis
The Department of Defense, through the Defense Advanced Research Projects Agency, is seeking innovative solutions under this SBIR opportunity to develop and demonstrate compact, wideband tunable radio frequency filters. The core objective is to design, model, and fabricate power-efficient filters operating in the 2 to 18 GHz range that protect wideband receivers from external interference and jamming. Work is divided into a 6-month Phase I focused on analytical modeling and design, followed by a Phase II of up to 36 months to fabricate and package five or more functioning prototype filters. Technical requirements demand a center frequency tuning ratio of at least 4 to 1, packaged sizes under 20 cubic centimeters, and power consumption under 250 milliwatts. Interested small businesses must submit their proposals before the application deadline on June 24, 2026.
