What Ditom Microwave does
DiTom Microwave is a Fresno, California-based manufacturer of passive RF components — specifically RF isolators and RF circulators — founded in 1987 and operating as a privately held company. The company specializes in high-reliability hardware for space, defense, military aerospace, SATCOM, 5G, and emerging quantum computing applications, alongside commercial off-the-shelf wireless infrastructure. Its customer mix spans engineered-to-order defense and aerospace programs and catalog-based commercial buyers.
Its product portfolio centers on two core component types: single and dual junction isolators that provide port-to-port isolation, and 3- and 4-port circulators that route RF signals directionally. The catalog covers frequencies from approximately 0.4 GHz to 43.5 GHz with SMA, N-type, K, and 2.4mm connector options. Differentiated product lines include cryogenic isolators and circulators engineered for 4K and 77K operation in quantum computing systems, space-qualified models (DSI/DSC series) for spacecraft integration, thermal vacuum (TVAC) qualified hardware (DVI/DVC series), Hi-Rel military-qualified components (DHI/DHC series), and Q-Band hardware reaching 43.5 GHz. The company operates an on-site environmental test laboratory supporting custom ATP/QTP development and unique SCDs per part number, and maintains 320+ models in inventory with 1000s of parts ready for next-day shipment.
DiTom generates revenue through unit sales of physical RF hardware via a tri-channel go-to-market: a direct e-commerce storefront on ditom.com with online ordering and connector customization, an authorized distributor network, and regional manufacturer representatives. Pricing is volume-tiered (1–24 units at standard pricing, 5% discount at 25–99 units, 8–10% discount at 100+ units), with custom configurations quoted within two business days and in-stock items shipping within one business day. The company serves seven primary use-case segments — cryogenic quantum computing, commercial wireless/COTS, SATCOM, RF test labs/5G/broadband, space qualified, TVAC, and military aerospace — and participates in industry events such as IMS 2026 (Booth #14024, Boston) for ecosystem visibility.
