Very Wide Bandwidth Radar/EW Components and Characterization

This proposal is focused on the development of very wide bandwidth, high efficiency power amplifiers for next generation EW, radar and wireless communication systems. High-Q tunable notch filters, coupled with high efficiency power appliers (PA) will be designed and analyzed. The PA-filter co-design techniques is expected to produce very wide bandwidth, high efficiency power amplifiers with bandwidths greater than 4 to 1 and efficiencies greater than 60 percent across the operating band. A prototype proof-of-concept PA-filter module will be developed for operation from L Band to C Band in the first phase of the project. The concepts developed for the prototype L to C band amplifier will then be applied to higher frequency designs with the goal of extending the concept for high efficiency, very high bandwidth power amplifiers through 110 GHz.
