New Approaches to Low Loss Flexible Coaxial Cable Designs

摘要

Unique dielectric and outer conductor constructions combined with optimized jacketing have produced flexible, low-loss cables possessing a high degree of stability. Current effort in this program is being directed in the areas of possible reduction of dielectric loss, substitution of polyethylene for Teflon to reduce costs, and the development of suitable connectors for terminating the cables. It is planned to utilize QL connectors for the larger cables (US-5 and US-10) and N connectors for the US-15 cable. The significant reduction in conductor loss achieved by the copper tape wrap and braid design has suggested extrapolation of this technique to standard solid dielectric cables. This construction also gives rise to the expectation of improved shielding characteristics. (Author)
