Summary

The Department of War Air Force AFMC seeks SBIR proposals to develop miniature, low‑power, continuously tunable notch filters that protect wideband receivers from large interferers across L, S, C and X bands. The filters aim to enable a single high‑dynamic‑range receiver to replace multiple narrowband units, reducing size, weight, power and improving electronic warfare, signals intelligence and communications capabilities.
