Microphase Corp

Microphase Corp, doing business as Microphase Holding Co LLC, manufactures specialized radio frequency, microwave, and millimeter wave electronic components and filters for the Defense Logistics Agency and the Department of the Navy as a small business prime contractor, with 98% of recent awards issued as purchase orders and delivery orders under its own contracts or parent Indefinite Delivery Contracts rather than through set-asides.

Microphase is a for-profit manufacturer headquartered in Shelton, Connecticut, and a subsidiary of Giga-Tronics Incorporated. The company specializes in band pass filters, radio frequency detectors, video sign detectors, multiplexers, and semiconductor devices serving defense and aerospace applications. Microphase registered as a federal contractor in 2001 and competes in full-and-open procurements without set-aside designations on most awards, though it qualifies for Total Small Business set-aside contracts when issued.

Customer concentration sits heavily with the Defense Logistics Agency across two divisions. DLA Land and Maritime dominates both volume and potential value with 283 awards worth $4.7 million combined potential value, accounting for 38% of all recent awards. DLA Aviation follows with 121 awards worth $2.9 million. The Department of the Navy (116 awards, $935 thousand combined potential value) and the Department of the Navy Naval Supply Systems Command (21 awards, $378 thousand) account for a secondary but active customer base. These five customer entities represent 78% of all recent awards and 81% of combined potential value, reflecting a highly concentrated, defense-logistics-focused footprint.

Microphase's primary vehicle is an Indefinite Delivery Contract with DLA Aviation valued at $250,000 through April 2028, designated as a Total Small Business set-aside, under which the company supplies video sign detectors (NSN 4610100925) on an as-needed basis. Recent delivery orders against this IDC range from $22,620 to $103,140 in individual ceiling values. Additional IDV activity flows through multiple DLA Land and Maritime Indefinite Delivery Contracts, with recent task orders carrying ceilings of $4,470 to $56,580 for radio frequency filters and band pass filters. Recent representative prime awards include a $56,580 Total Small Business set-aside purchase order from DLA Land and Maritime for radio frequency filters (August 2025), a $103,140 purchase order from DLA Aviation for detection equipment (July 2025), and a $83,031.14 Total Small Business set-aside purchase order from DLA Land and Maritime for 38 units of radio frequency filters (April 2025).

Activity has accelerated year over year, from eight awards in 2022 to 22 in 2024 and 24 in 2025 (through mid-November). Combined potential value across all 744 awards totals $12.1 million, though combined dollars obligated reach $28.2 million, reflecting significant exercise of options and delivery order funding against standing Indefinite Delivery Contracts. No recompete cliff is surfaced in the source data.

In its subcontractor role, Microphase supplies filters, multiplexers, and RF detectors to major defense primes. Named subcontract relationships include Lockheed Martin (PAC-3 missile coaxial assembly filters and low-pass filters across multiple 2022–2024 modifications), Raytheon (filters and multiplexers for Romania production and UCA systems, 2025), Sierra Nevada Company (filters, 2024), BAE Systems Information and Electronic Systems Integration (frequency converter and video detector log amplifier, September 2025), Caes Systems (non-recurring engineering for AEA assembly and RF detectors, 2024–2025), and Seacorp LLC (tri-band pass filters, 2025). The vendor's subcontract footprint represents 2% of recent awards by count but anchors strategic defense prime relationships in advanced weapons systems.

Microphase's award portfolio centers on Filters and Networks (213 awards by PSC), Miscellaneous Communication Equipment (240 awards), Electronic Countermeasures and Related Equipment (91 awards), and Other Communications Equipment Manufacturing (153 awards by NAICS), reflecting its role as a specialized component supplier across defense communication, detection, and signal processing applications.
