The Department of Defense (DOD) is seeking proposals for a research topic titled "Low-Cost, High-Power Microwave Switches for Radar and Electronic Warfare (EW) Applications" under the SBIR program. The Navy branch is specifically interested in this topic. The objective is to design, optimize, and fabricate prototypes for a low-cost, low-loss, high-power microwave switch with fast-switching speeds over large instantaneous bandwidths. The switch should be suitable for radio frequency (RF) surveillance and EW applications. The Navy is looking for novel methods to produce low-cost, high-power microwave switches that improve power handling, tuning speed, efficiency, and linearity while reducing unit cost. The proposed switch should operate within the frequency range of 2-12 GHz (threshold) or 2-18 GHz (objective) and meet specific performance metrics for power handling, insertion loss, isolation, switching speed, cycles, linearity, and duty cycle. The Phase I of the project involves developing a preliminary design and simulated results of the switch, while Phase II focuses on producing prototypes and conducting laboratory-based testing. The Phase III aims to design and deliver higher-level subassemblies incorporating the new switching technology for both DoD and commercial applications. The project duration and funding specifics can be found in the solicitation notice on grants.gov or the DOD SBIR/STTR Opportunities website.
