COMPACT WIDEBAND TUNABLE FILTERS
SBIR Opportunity Analysis
DARPA, within the Department of Defense, is seeking SBIR solutions for compact, wideband tunable RF filters to improve spectrum access and signal integrity for communications and electronic warfare systems. The work calls for power-efficient filter technologies that can protect wideband receivers from external interference and jamming, with Phase I centered on design, modeling, and proof-of-concept validation. Phase I targets a 2 to 18 GHz operating range with at least 4:1 center-frequency tuning and 3:1 bandwidth tuning, along with strong insertion loss, rejection, size, and power-performance characteristics; Phase II would extend to fabrication and demonstration of five or more functioning packaged filters. The opportunity is open, with proposals due June 24, 2026 at 4:00 PM UTC.
