Virginia Diodes, Inc.

Virginia Diodes, Inc., a small business manufacturer of millimeter-wave and terahertz electronic devices based in Charlottesville, Virginia, operates as a prime contractor on federal purchases and SBIR awards across research and measurement applications, competing predominantly under total small business set-asides on SBIR work and full-and-open on specialized equipment sales.

The company manufactures concrete hardware for high-frequency applications: vector network analyzer extender heads and frequency extension modules (110–170 GHz and above), up-converters and down-converters for terahertz communications, noise sources and local oscillator modules for the 0.1–1.0 THz and terahertz frequency ranges, mixer-amplifier chains, multipliers, and receiver front-end assemblies for remote sensing and radiometry. Representative work includes a $1.799 million firm fixed-price DARPA contract awarded December 2022 for high VSWR mechanical tuners critical for noise and load-pull measurements in the millimeter-wave frequency range (ultimate completion February 2026), a $1.543 million NASA Phase III SBIR for POLSIR receiver and optical subassembly development (February 2024), a $1.17 million NASA Phase III SBIR for Aurora 109–192 GHz spectrometer front-end electronics awarded September 2025, and two Phase II SBIR awards from NASA's Shared Services Center in August 2025 valued at $849,999 for terahertz mixers and receivers and $850,000 for 0.1–1.0 THz noise sources. Most recently, the National Institute of Standards and Technology awarded an $83,200 total small business set-aside purchase order in April 2026 for WR6.5 Tx/Rx VNA Extender Head modules.

Customer concentration is marked by heavy reliance on research agencies. NASA's Shared Services Center leads the portfolio with 42 awards and $12.4 million in combined potential value, followed by the Office of Naval Research (38 awards, $2 million), the Smithsonian Institution (34 awards, $561 thousand), the National Institute of Standards and Technology (27 awards, $1.4 million), and the Army Materiel Command Research Development and Engineering Command (13 awards, $3.1 million). These five customers account for 66% of awards and 69% of combined potential value. The split between these rankings — NASA anchors both volume and dollars while the Army ranks second by value but fifth by count — reflects the company's mix of high-value multi-year SBIR Phase II and Phase III contracts alongside numerous smaller purchase orders for measurement equipment.

Award activity has declined from 13 awards in 2022 to 7 annually in 2023–2025, with only one award recorded to date in 2026. Three awards carrying combined potential value of $2.9 million face ultimate completion within the next twenty-four months. The company holds no positions on government-wide IDIQs, GWACs, or BPAs; awards are structured as direct purchase orders and definitive contracts. Virginia Diodes acts as prime on all tracked awards (100% of the portfolio), with a single subcontract recorded to Northrop Grumman Systems Corporation in July 2022. In addition to contract work, Virginia Diodes received a $299,996 Project Grant from the National Institute of General Medical Sciences (CFDA 93.859, Biomedical Research and Research Training) awarded May 2025 for development of solid-state microwave sources for Dynamic Nuclear Polarization NMR instrumentation, with completion scheduled April 2026. The company's primary NAICS classification reflects instrument manufacturing (84 awards) and electronic component manufacturing (40 awards), with secondary NAICS in research and development and semiconductor manufacturing. Equipment categories emphasize electrical and electronic properties measurement instruments (45 awards), laboratory equipment and supplies (33 awards), and antennas and waveguides (25 awards).
