About this opportunity
Air Force SBIR topic — Accepting submissions 2026-12-02 to 2027-01-06. The objective of this topic is to develop miniature, low power, and high selectivity tunable notch filters capable of protecting wideband receivers from large interferers. The effort will target the largest interferers which are in L, S, C, and X bands with tunable notch filters, while allowing pass bandwidths spanning L through Ku bands. Each notch filter must be continuously tunable across a minimum of 3 of the 4 targeted bands (L, S, C, and X) while having a notch depth > 20 dB and a notch bandwidth < 1 % across all tuned frequencies. With a narrow notch bandwidth, each notch filter must be programmable and maintained with an accuracy of 50% of the notch bandwidth and should maintain this accuracy over temperature. ...
