Innovation and Performance for 75 Years


Winchester Electronics has created breakthrough RF and microwave cable and interconnect products for 75 years. Our sophisticated, durable, high-performance cables, connectors and interconnect systems are used in the most demanding applications—in military, aerospace, semiconductor, broadcast, medical, test & measurement and other industrial and commercial industries.

Winchester draws from the technical expertise of time-tested, well-respected RF brands TRU®, Haverhill, SRC, KINGS®, and Bomar. Whether your application calls for durability, flexibility, reliability, or performance—or combinations of these—Winchester’s formidable lineup of RF Microwave flexible, conformable, and semi-rigid cable solutions can address your most challenging requirements.

Winchester’s superior design and construction offer some of the broadest frequency, highest-power, lowest-loss, most phase/amplitude-stable, and highest-flexibility products on the market. Winchester cable means quality across the broadest spectrum of power and frequency—from 50 kilowatts to 50 GHz. Durable, lightweight, low-loss, high-frequency, phase-stable, small-signal, and high-power cables can all be engineered for your specific applications.

Our experts are always available to answer any of your technical or design-related questions, and to work with your own design team.
