NTB Series Cable

Ultra-Low Loss Phase Stable Coaxial Cable

The NTB cable series provides higher performance, typical low loss and phase stable cables. It offers extra low loss, light weight, and high phase stability versus mechanical and temperature change. This cable series features a silver-plated copper center conductor, low density PTFE dielectric, silver-plated copper tape wrapping outer conductor, silver-plated copper braid shield, and grey FEP outer jacket.

NTB series cable accepts standard solder-on connectors. Typical applications include military and phased-array radars, electronic warfare (EW), and mechanical equipment. It is available for quick delivery as cable or finished cable assemblies with custom labeling. We can also provide phase matching assemblies up to 67 GHz. There is no minimum order quantity.
