Description
50 Ohm Semi-Rigid Coaxial Cable | Copper Shield | PTFE Dielectric
The ROSNOL RSR-047 is a 50 Ohm semi-rigid coaxial cable designed for high-frequency microwave applications up to 65 GHz. It features a steel inner conductor plated with copper and silver (∅0.287 mm / 0.0113 in), PTFE dielectric, and a solid copper outer shield (∅1.19 mm / 0.047 in). With a minimum bending radius of 1.91 mm (0.08 in) and weight of 5.7 g/m, the cable supports operating temperatures from -40°C to +125°C.Electrical performance includes 95.1 pF/m capacitance, 69.5% signal velocity, and shielding effectiveness better than -110 dB up to 18 GHz. Typical attenuation ranges from 0.79 dB/m at 0.5 GHz to 12.85 dB/m at 65 GHz, with maximum CW power handling of 67.5 W at lower frequencies. The RSR-047 is RoHS compliant and ideal for compact, precision RF systems.
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. All ROSNOL cables are fully compliant with global environmental and safety regulations, including RoHS and REACH. Customization services for materials, shielding, and mechanical design are available to support specialized application requirements.
