Description
50 Ohm Semi-Rigid Coaxial Cable | Copper Shield | PTFE Dielectric
The ROSNOL RSR-085 is a 50 Ohm semi-rigid coaxial cable designed for microwave applications up to 50 GHz. It features a steel inner conductor plated with copper and silver (∅0.51 mm / 0.0200 in), PTFE dielectric, and a solid copper outer shield (∅2.20 mm / 0.0865 in). With a minimum bending radius of 1.27 mm (0.0500 in) and weight of 21.3 g/100m, the cable supports operating temperatures from -40°C to +125°C.Electrical specifications include 95.2 pF/m capacitance and operating voltage up to 1.5 kVrms. Typical attenuation ranges from 0.45 dB/m at 0.5 GHz to 5.7 dB/m at 50 GHz, with maximum CW power handling of 232 W at lower frequencies. The RSR-085 is RoHS compliant and suitable for high-frequency RF systems requiring stable performance and shielding effectiveness up to -110 dB.
ROSNOL’s cable solutions are precision-engineered to meet the rigorous demands of RF and microwave transmission systems. Manufactured under ISO 9001-certified processes, ROSNOL cables deliver consistent high quality and performance at competitive pricing, making them a reliable alternative to products from leading European and American brands.
