What East Coast Microwave does

East Coast Microwave (ECM), Sales & Distribution LLC is a privately held, franchised specialty distributor and value-added manufacturer of RF and microwave interconnect solutions headquartered in Woburn, Massachusetts. Founded in 1980, the company distributes over 20,000 SKUs spanning coaxial connectors, cables, adapters, cable assemblies, and complementary RF components including amplifiers, attenuators, circulators, couplers, switches, waveguide components, and calibration tools. The Woburn facility is AS9100D and AS9120B certified, ITAR registered, and REACH/RoHS compliant, and also serves as the site for in-house custom cable assembly manufacturing.

ECM operates a hybrid distribution-plus-value-added-services model. Approximately 18 franchised line card relationships with manufacturers including Radiall, Huber+Suhner, Corning Gilbert, SV Microwave, Amphenol RF, Amphenol CDI, Times Microwave Systems, Anritsu, DITOM, Southwest Microwave, TE Connectivity, XMA, RF Industries, Winchester, Samtec, Rosenberger, Micro-Coax, and Low Noise Factory supply the catalog breadth, while in-house Value-Added Services build custom RF cable assemblies supporting VITA 67.1, 67.2, 67.3, and VITA NanoRF interfaces with 2-week standard lead times and 24-hour rush delivery. Assembly work is performed by IPC/WHMA-A-620 certified staff. Pricing is quote-based via an online RFQ submission system that allows customers to upload BOMs and target prices.

The company targets defense and military (primary), semiconductor test, test and measurement, industrial/robotics, and broader RF/microwave industry buyers through a sales-led go-to-market combining a website e-catalog, vertical-specific industry brochures, RFQ portal, and direct phone support (1-800-STOCKROOM in North America). No public revenue, funding, or investor disclosures are available; ownership appears to be private and management-led.
