It covers DC to 26.5 GHz at a 50 Ohm characteristic impedance — the full bandwidth of the SMP interface. Gold plating on both the beryllium copper body and centre contact gives it the corrosion and mating-cycle life needed for repeated test or field connections over its 100-cycle rated life. The snap-on fastening provides quick, positive engagement without a coupling nut — standard for SMP blind-mate or push-on applications. ## What cable does it work with? This plug is built for RG-178 cable — the 0.072-inch diameter, 50 Ohm, PTFE-dielectric coax commonly used in tight-bend RF interconnects. The solder termination on the shield and centre conductor matches the standard RG-178 prep dimensions. The included ferrule crimps over the cable jacket for strain relief. No other cable group is listed as compatible. ## Temperature and environment The PTFE dielectric maintains stable impedance across that range, and the gold-over-beryllium copper contacts resist oxidation at the high end. The silver-coloured housing is bare beryllium copper with gold finish; no IP rating is listed, so it is not sealed against moisture ingress without added booting.","metaTitle":"SMP-FR-C19 SMP Plug, 50 Ohm, 26.5 GHz, RG-178 Cable","metaDescription":"SMP-FR-C19 SMP plug male pin, 50 Ohm, DC-26.5 GHz, for RG-178 cable.
