DIAMOND ANTENNA & MICROWAVE CORPORATION

Diamond Antenna & Microwave Corporation specializes in the design, manufacture, and repair of high-precision microwave and RF components for defense and aviation systems, with deep expertise in rotary couplers, radar interfaces, and waveguide assemblies. The company’s technical capabilities center on custom electronic component manufacturing for radar, navigation, and communication systems, including the overhaul and refurbishment of critical subsystems such as AN/SPN-43C rotary couplers and TDWR/ASR-9 radar components. Their work supports active-duty military platforms and FAA air traffic control infrastructure, demonstrating proficiency in maintaining mission-critical RF performance under stringent environmental and operational conditions. Differentiators include precision machining of microwave-grade materials, RF signal integrity validation, and the ability to reverse-engineer legacy components for continued system sustainment. The contractor maintains a strong, sustained relationship with the Department of Defense, delivering components and repair services for naval, air, and land-based radar systems, while also serving the Department of Transportation through FAA programs involving terminal Doppler weather radar and surveillance infrastructure. Their work for these agencies consistently involves sustainment of aging, high-reliability systems requiring strict adherence to military and aviation technical specifications. Industry focus is anchored in NAICS 334419 (other electronic component manufacturing) and 334511 (aeronautical and navigation instrument manufacturing), with secondary activity in 334220 (wireless communications equipment). This positions the company as a niche supplier for RF subsystems in defense and air traffic control ecosystems, where component longevity and signal fidelity are paramount. Diamond Antenna & Microwave Corporation is a small business headquartered in Littleton, Massachusetts, with no formal government certifications on record. Its operational footprint is centered on precision manufacturing and repair services tailored to federal defense and aviation customers, operating as a trusted, specialized vendor within the government’s sustainment supply chain.
