D-COAX, Inc. D-COAX d086 Series Cable Pair High Frequency, Skew Matched, Phase Stable Cable Pair (65 GHz) D-COAX d086 Series Cable Pair consists of two skew matched (to 1ps) flexible cable assemblies with 1.85 mm male connectors on both ends. The d086 series cable is a low loss and phase stable cable. This cable utilizes silver plated copper conductor, with a very low loss expanded PTFE dielectric. The shield consists of two conductive layers: the first layer is a silver plated copper flat wire, applied in such manner that it yields low contact resistance resulting in low insertion loss, the second layer is a silver plated copper braided shield that contributes to excellent RF leakage characteristics, specified at > -100 db to 18 GHz. The standard outside jacket is a tough, resin melt extruded ETFE. This assembly uses impedance-matched 1.85mm connectors to accomplish low return loss up to 65 GHz. These assemblies will make great and cost effective test cables. D086 Series cable pair is available in custom lengths also. 1
