Flexco Microwave

What Flexco Microwave does

Flexco Microwave Inc. is a privately held, family-run US manufacturer of custom and off-the-shelf flexible coaxial cable assemblies, founded in 1970 by engineer William T. Pote and headquartered at 17 Karrville Rd, Port Murray, New Jersey, with manufacturing facilities in Hackettstown and Port Murray, NJ (approximately 38,000 sq ft combined). The company pioneered flexible coaxial cable technology with two patented innovations that define its product architecture: (1) a sealed outer conductor formed from a continuous copper strip with a completely soldered seam, eliminating dependence on surface contact area, and (2) an air-articulated PTFE dielectric with calculated helical cuts that approximates an "air line" design and transfers heat more rapidly than solid dielectrics. Together these designs maintain concentricity between inner and outer conductors during repeated flexing, yielding phase and amplitude stability under mechanical stress that the company reports as a zero-change-in-electrical-performance outcome.

Flexco's product portfolio is organized into four series: the SLL (Super Low Loss) Series for telecom and wireless base-station interconnect, the Performance Series for aerospace and space qualifications (TIROS, DMSP, SATCOM programs since 1974), the KW and S-Series for high-power applications (wafer fabrication, industrial lasers, FAA and military radar transmitters), and the NTC Series Test Cables for precision RF/microwave test and measurement. Products span DC to 50 GHz with documented insertion-loss figures per model, operating temperature ranges of -75°C to +135°C, and space-qualified storage life of 7+ years and operational life of 3+ years. The company serves defense primes (Raytheon, Lockheed Martin, Northrop Grumman), government agencies (NASA, JPL, FAA), satellite operators (Comsat, Globalstar, Iridium, L3 Harris/Randtron), semiconductor equipment makers (LAM Research, AML Communications), and historical wireless infrastructure customers (Motorola, Nortel, Lucent).

The revenue model is quote-based hardware sales of both custom-engineered and standard assemblies, with multi-year contract cadence typical of defense and aerospace procurement. Pricing is set through a website request form followed by direct sales engagement, supported by a global channel of exclusive foreign representatives across 15+ countries in Europe (Elhyte, Amska, Aviatronik, Spantech), Asia-Pacific (Tatitek KK, Tect Electronics, plus India and Korea coverage), the Middle East (Cidev Group in Israel), and a dedicated US government aftermarket representative (Dutch Valley). Flexco is ISO 9001:2015 (ANAB) certified, ITAR registered with the US Department of State, and qualified to MIL-STD-2000, NHB 5300.4 3A-2, MIL-I-45208, and NASA-STD-8739.3, supporting its positioning in defense, space, and high-reliability commercial applications. The company employs 11–50 people with an average tenure of 12 years, transitioned from military-only to include commercial markets in 1995, and was honored with the Raytheon Supplier Excellence Award in 2023.
