Quarterwave Corp.

Quarterwave Corp., a for-profit manufacturer of specialized electronic components based in Rohnert Park, California, supplies power supply modules, traveling wave tube amplifiers (TWTAs), and related radar and aviation electronics to federal agencies as a prime contractor (98% of recent awards), competing exclusively on full-and-open procurements without set-aside designations.

Quarterwave operates across two primary capability domains grounded in its recent contract work. The first centers on power supply modules for the FAA's Airport Surface Detection Equipment (ASDE)-3 radar system across National Airspace System locations. Quarterwave holds proprietary design and manufacturing data for ASDE-3 power supply modulators, which has driven multiple sole-source and competitive procurements from the FAA for repair, refurbishment, modification, and new manufacture of these components. Recent representative awards include a $575,220.80 sole-source definitive contract from the FAA on June 22, 2026 for power supply modulator units (NAICS 335311, Power, Distribution, and Specialty Transformer Manufacturing), a $1.575 million firm fixed-price contract from June 4, 2024 for procuring a minimum of 45 ASDE-3 power supply modulators driven by obsolescence and parts unavailability, and a $937,860 definitive contract from August 20, 2025 awarded after an FAA market survey seeking alternative ASDE-3 module suppliers. The second capability domain involves rebuild, upgrade, evaluation, and repair of high-power, low-noise traveling wave tube amplifiers (TWTAs) for naval and air force platforms. Representative work includes a $173,905.06 sole-source purchase order from Naval Sea Systems Command in January 2024 to rebuild and upgrade three TWTA units for Naval Surface Warfare Center Carderock Division, a $123,504.12 order from the Air Force Materiel Command Oklahoma City Air Logistics Complex in November 2022 for delivery of one TWTA model 9108/95400-H75J18, and a $68,610.91 order from the same logistics complex in May 2023 for radome test transmitter rebuild.

Customer concentration splits between two agencies. The Department of Transportation Federal Aviation Administration dominates by dollar value, with FAA's Franchise Acquisition Services office holding five awards worth $4 million combined (58% of total potential value across all awards), while the Department of the Navy splits across Naval Sea Systems Command (14 awards, $546 thousand) and the broader Navy entity (11 awards, $565 thousand), accounting for 33% of total potential value. The FAA alone represents 81% of combined potential value across the top five customer lines. Quarterwave places work under Navy indefinite delivery contracts N6893602D0035 (2 task orders, $565 thousand) and N6893695D0394 (2 task orders), and FAA contract FA853020D0001 (1 task order). Awards skew toward small-dollar purchase orders for discrete component evaluation, repair, or supply, with only one subcontract on record — a December 4, 2023 sub-award under Mercer University on aging bomber aircraft electronic combat subsystems engineering services. Activity has remained modest and flat over the past four years (four awards in 2022, five each in 2023 and 2024, one each in 2025 and 2026 year-to-date), with only one award reaching ultimate completion within the next twenty-four months ($575 thousand potential value due December 19, 2026). Total awarded footprint across 64 prime and sub awards spans $6.8 million in combined potential value, with actual obligations at $7 million (103% of potential value), indicating full or near-full spend across the recorded portfolio.
