Description
50 Ohm Semi-Rigid Coaxial Cable | Copper Shield | PTFE Dielectric
The ROSNOL RSR-085C is a 50 Ohm semi-rigid coaxial cable engineered for microwave systems up to 61 GHz. It features a silver-plated copper inner conductor (∅0.51 mm / 0.0201 in), PTFE dielectric (∅1.68 mm / 0.0661 in), and a solid copper outer shield (∅2.18 mm / 0.0858 in). With a minimum bending radius of 10 mm (0.3937 in), the cable supports operating temperatures from -55°C to +125°C.Electrical performance includes 98 pF/m capacitance, 70% signal velocity, and shielding effectiveness > 110 dB up to 1 GHz. Typical attenuation ranges from 0.45 dB/m at 0.5 GHz to 3.29 dB/m at 20 GHz, with maximum CW power handling of 190.3 W. The RSR-085C is RoHS compliant and ideal for precision RF applications requiring enhanced shielding and thermal stability.
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.
