Dow-Key Microwave LLC

Dow-Key Microwave LLC, a for-profit manufacturer of radio frequency and microwave electronic components and subsystems, operates as a subsidiary of MPG Holding Company and competes as a prime contractor (66% of recent awards) and subcontractor (34%) on full-and-open federal procurement with no small business set-asides across its portfolio. The company is headquartered in Ventura, California and manufactures mission-critical RF switches, switch matrices, relays, and related high-precision electronic components for defense, aerospace, and space applications.

Dow-Key Microwave's capability portfolio centers on RF and microwave switching technologies. Representative prime work includes a $643,743 firm-fixed-price purchase order from the Office of Naval Research for a 9x8 full fanout analog RF switch matrix (August 2021), a $145,008 purchase order from the Air Force Materiel Command Test Center for a multi-switch RF unit (September 2022), and a $127,337 Office of Naval Research sole-source purchase order for an SS SP9T switch (December 2022). More recent prime awards include a $35,200 purchase order from Naval Supply Systems Command for switch repair and maintenance of EA-18G Growler fleet assets (August 2025), a $59,160 purchase order supporting National Airspace System assets (June 2025), and a $15,200 Office of Naval Research purchase order for sixteen RF transfer switches (March 2026). The company's contract portfolio reflects its specialization in aircraft avionics and electronic warfare systems sustainment.

Customer concentration is heavily skewed toward Navy technical and operational commands. The Office of Naval Research accounts for 38 awards valued at $13.4 million—93% of the company's combined potential value across all 240 awards. The Naval Sea Systems Command (30 awards, $194 thousand) and Naval Supply Systems Command (18 awards, $112 thousand) rank second and third by volume, with the Air Force Materiel Command (18 awards, $29 thousand) and Defense Logistics Agency (13 awards) rounding out the top five by award count. Across all distinct customer agencies served (45 total), the top five account for 49% of awards, and the top five by potential value account for 93% of combined potential value—an exceptionally narrow customer concentration driven entirely by Navy spend.

Dow-Key Microwave places task orders under Air Force and Navy IDIQs, including Indefinite Delivery Contract FA854019D0001 (16 task orders), Indefinite Delivery Contract N0017314D2006 (5 task orders, $3.6 million combined potential value), Indefinite Delivery Contract N6660420DR000 (5 task orders), Indefinite Delivery Contract W58RGZ24D0065 (5 task orders), and Basic Ordering Agreement FA862021G4027 (3 task orders). The vendor's top PSC categories are Antennas, Waveguides, and Related Equipment (45 awards) and Switches (40 awards), with secondary exposure in Relays and Solenoids (9 awards) and Electronic Modules (7 awards).

Award activity has accelerated in recent years—five awards in 2022, twenty in 2023, twenty in 2024, and forty-five in 2025—though the first quarter of 2026 shows only one award to date. The recompete cliff is minimal: only one award with ultimate completion inside the next twenty-four months carries $15 thousand in potential value. Dow-Key Microwave subcontracts extensively to major primes, delivering RF switches and switch matrices to Northrop Grumman Systems Corporation on Litening Advanced Targeting Pod programs (multiple awards July 2025), L3Harris Technologies and L3 Technologies on Counter Communications Systems and Manned/Unmanned Teaming platforms (multiple awards through October 2025), Raytheon Company on guided missile and air defense system production (multiple awards including Romania Production UCA RF Switches, June 2025), Lockheed Martin on Global Positioning System III Follow On space vehicles (multiple awards including S-band switch matrix assemblies), Serco Inc. on radio frequency distribution and control systems (multiple awards July 2025), and Assurance Technology Corporation on TERFS and related RF products (multiple awards December 2023). The company's subcontract footprint spans defense, space, and intelligence platforms across the full technology stack of carrier aircraft, missile systems, radar, and satellite communications.
