Summary
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.
