Exponential Technology Group, Inc.

Exponential Technology Group, Inc. (doing business as Rfmw), a San Jose, California-based subsidiary of Berkshire Hathaway Inc., distributes RF and microwave components including amplifiers, filters, switches, mixers, attenuators, connectors, and integrated circuits to the Department of Defense and civilian federal agencies as a prime contractor (15% of recent awards) and predominantly as a subcontractor (85% of recent awards) to major primes.

Rfmw operates in the full-and-open competitive space with no set-aside designation on recent prime awards. The company competes across purchase orders and firm fixed-price contracts, with one Air Education and Training Command purchase order ($68,366.40, July 2024) designated for Total Small Business. Recent prime work includes a $127,270 Naval Air Warfare Center purchase order for physical and dimensional calibration standards (September 2025, completing July 2026), a $127,009.48 Naval Sea Systems Command order for cable assemblies under Carlisle Interconnect brand (April 2024), a $95,423.40 Naval Sea Systems Command order for communication equipment cable and wire assemblies (July 2024), a $71,213.24 Naval Sea Systems Command order for cable assemblies (December 2024), and multiple smaller awards across GSA's Shared Services Center and Naval commands for beamforming integrated circuits, power amplifiers, RF couplers, and specialized electronic components. The company's customer base spans 29 distinct federal agencies, with the top five by award count — the Department of the Army Acquisition Support Center PEO Missiles and Space (32 awards), the Department of the Army (23 awards), Naval Sea Systems Command (22 awards, $677 thousand combined potential value), the Department of the Air Force (18 awards, $72 thousand combined potential value), and the Department of the Air Force Materiel Command Lifecycle Management Center at Eglin Air Force Base (9 awards) — accounting for 61% of awards. Navy programs (Naval Sea Systems Command, Naval Air Systems Command, Naval Information Warfare Systems Command combined) anchor 89% of combined potential value.

Activity has accelerated sharply — nine awards in 2022 to seventy in 2024, with fifty-five in 2025 — though potential value across the footprint remains modest at $1.1 million despite $18.1 million in obligated dollars, reflecting the preponderance of small purchase orders. Only one award faces ultimate completion within the next twenty-four months, indicating minimal recompete cliff exposure.

Rfmw's subcontract portfolio is substantial and deep. The vendor supplies RF and microwave components to Lockheed Martin (PATRIOT PAC-3 missile production, A4 Sentinel radar systems, advanced radar threat systems, JASSM and LRASM programs, ngI AUR development, and integrated logistics support), Raytheon (AMRAAM production lots 37 through 40, GMA C-band systems, CIWS long-term contract, TOW missile production, Taiwan surveillance radar follow-on support, and Birdseye Yonder), L3 Technologies and L3Harris (counter communications systems, manned-unmanned teaming platforms, MUMT-X production for Qatar and Morocco, and NGJ low-band development), and Northrop Grumman (AN/ALQ-251 configuration development for the Royal Australian Air Force C-130J program). Additional subcontract relationships span BAE Systems (BIG Safari diversity switches), Scientific Research Corporation (NIWC Atlantic RF distribution units), Lockheed Martin (B-1B DSU RF subsystems, AEGIS hardware dividers), Boeing (Wideband Global Satellite Communications, MUOS service life extension), Honeywell Federal Manufacturing (National Security Campus management and operations), and smaller primes including Torch Technologies, Marvin Engineering, and Assurance Technology. The source indicates Rfmw's primary NAICS concentration in guided missile and space vehicle manufacturing (48 awards), research and development in physical and engineering sciences (28 awards), and search, detection, and navigation system manufacturing (25 awards). The company participates under parent vehicles including Army indefinite delivery contracts W56KGY-22-D-0001 (8 task orders) and W58RGZ-24-D-0065 (6 task orders), and the Eglin Wide Agile Acquisition Contract (4 task orders). Rfmw was established in 2019 and operates as a specialized RF and microwave distributor with established relationships across the defense industrial base.
