The Department of Defense (DOD) is seeking proposals for the topic "Scalable Wideband Multifunction Radio Frequency (RF) Payloads" as part of the SBIR 24.2 Annual solicitation. The objective is to design, develop, and demonstrate wideband multifunction RF payloads using a scalable Modular Open Systems Approach (MOSA) for Unmanned Aerial Systems (UAS) Groups 1 through 3. The payloads should have capabilities in Electronic Warfare (EW), Radar, Command, Control, Computing, Communications, Cyber, Intelligence, Surveillance, Reconnaissance, and Targeting (C5ISRT), and edge-based High-Performance Computing (HPC). The desired technology should adhere to Size, Weight, and Power and Cost (SWaP-C) constraints and conform to ANSI/VITA standards. The proposal should include a highly-scalable MOSA methodology and system architecture, prototype plans, and evaluation of digital/mixed-signal processing and RF performance characteristics. Phase II involves producing a prototype payload and demonstrating modularity and scalability. Phase III focuses on further development, testing, and qualification for specific missions and aerial platforms. The technology has potential applications in various industries, including IoT, cellular technologies, satellite communications, RF test and measurement devices, and automotive and UAS radar. The proposal submission deadline is June 12, 2024. For more information, visit the DOD SBIR website.
