The Department of Defense (DOD) is seeking proposals for the topic of "Software Defined RadioHead (SDRH)" as part of their SBIR 24.4 Annual solicitation. The objective is to develop a radio agnostic SDRH system that can rapidly adapt the radio carrier frequency among diverse targeted frequency bands using analog and/or digital frequency conversion. This technology will provide additional flexibility to the commander's communication plan. The SDRH design will be a flexible antenna prototype capable of supporting multiple frequencies and radio modules, complementing the C5ISR/CMOSS standard's objective for agnostic hardware. The solicitation is open for Direct to Phase II (DP2) proposals with a maximum cost of $2,000,000 for a 12-month period of performance. Phase II will involve developing a prototype SDRH for evaluation and testing by the U.S. Army Combat Capabilities Development Command (DEVCOM) C5ISR Center. The solicitation also highlights potential dual-use applications of SDRH technology in industries such as IoT, UAVs, smart cities, and mobile communications. The deadline for proposal submission is March 31, 2025. For more information, visit the solicitation link or the DOD SBIR/STTR Opportunities website.
