Coaxial cable applications range widely, from large CATV cables to ultra-small medical camera cables. Wherever a cable must be matched to a transmission system for data, audio, or video, New England Wire Technologies provides a solution. Whether the requirement is a standard 50-ohm coax or a fully custom design, we engineer, manufacture, and test each cable to precisely match the impedance, attenuation, and performance requirements of the system. Our test capabilities include frequency analysis up to 25 GHz, attenuation and impedance measurements, low-noise testing, and a broad range of additional electrical evaluations.
We support fully custom coaxial designs using a wide selection of materials. Center conductors are available in copper or copper alloy, copper-clad steel, or steel, and may be solid, stranded, bunched, or rope-lay depending on the AWG size and application. Dielectric materials are typically polyolefin or fluoropolymer, offered in either solid or foamed constructions. Polyolefins are well suited for lower-cost, lower-temperature applications, while fluoropolymers provide higher temperature ratings and improved electrical performance at increased cost. Our proprietary foamed dielectric, NEWcel®, available in both polyolefin and fluoropolymer versions, delivers superior electrical performance through reduced dielectric thickness and improved velocity of propagation (VOP).
Coaxial shielding options include wire and foil tape constructions. Wire shields may be spiral or braided and manufactured from copper or copper alloy for electrical conductivity, or steel for armored designs. Multiple shielding layers can be combined in various sequences to achieve specific design objectives such as flexibility, shield coverage, durability, and ease of termination. Jacket materials are selected to match application requirements and include PVC, TPU, TPE, polyolefin, fluoropolymer, and silicone rubber.
Coaxial cables can be designed to meet either impedance or capacitance targets, with typical values of 50 ohms, 75 ohms, or 30 pF/ft. Sizes range from 42–24 AWG for miniature and micro-miniature coaxes up to larger 1/0 AWG for high-power applications. Certain high-power coaxial designs incorporate Litz wire center conductors to reduce AC losses in high-frequency, high-power interconnections.
For applications where low-level signal integrity is critical, selected coaxial cables utilize our proprietary NEWtral® coating to minimize triboelectric noise.
We recognize the importance of transmission line performance in maximizing signal quality for high-frequency systems. Rather than adapting the system to a standard cable, we design and manufacture coaxial cables to match the characteristic impedance, capacitance, and attenuation requirements of each application. Standard coaxial cables for common use are also available and can be integrated into composite cable configurations.
Our broad manufacturing capabilities allow us to produce precision coaxial cables from ultra micro-miniature 50 AWG to 8 AWG and larger, in custom or standard configurations. Available constructions include shielded designs with round or flat braided wire, as well as spiral or foil-wrapped shields. We offer an extensive selection of dielectric materials, including polyolefin, polyethylene, polypropylene, and fluoropolymers such as ETFE, FEP, PFA, and PTFE (solid and low-density), along with custom dielectrics such as our proprietary NEWcel®.
