Description
50 Ohm Semi-Flexible Coaxial Cable | Tin-Plated Copper Shield | PTFE Dielectric
The ROSNOL RSF-085 is a 50 Ohm semi-flexible coaxial cable optimized for microwave applications up to 50 GHz. It features a steel inner conductor plated with copper and silver (∅0.53 mm / 0.0209 in), PTFE dielectric, and a tin-plated copper shield (∅2.17 mm / 0.0854 in). With a minimum bending radius of 3.2 mm (0.1260 in) and weight of 15 g/m, this cable is ideal for compact, high-frequency installations.Electrical specifications include 95.2 pF/m capacitance, 70% signal velocity, and 4.7 ns/m signal delay. It offers insulation resistance ≥ 1×10⁸ MΩ/m and screening effectiveness ≥ 100 dB up to 18 GHz. Typical attenuation ranges from 0.56 dB/m at 0.5 GHz to 6.84 dB/m at 50 GHz, with maximum CW power handling of 201.5 W. The RSF-085 is RoHS compliant and supports operating temperatures from -40°C to +120°C.
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.
