Description
50 Ohm Semi-Rigid Microwave Cable | Copper Outer Conductor | SPCW Centre Wire
The ROSNOL RSR-031-LL is a high-performance 50-ohm semi-rigid coaxial cable engineered for precision RF and microwave applications. Featuring a solid SPCW (Silver-Plated Copper Wire) center conductor and a low-density PTFE dielectric, this cable delivers consistent electrical performance across a broad frequency range. With a cutoff frequency of 180 GHz and attenuation values of 35.4 dB/100 ft at 0.5 GHz and 471.3 dB/100 ft at 90 GHz, it supports demanding signal integrity requirements. The cable withstands up to 1800 VRMS and operates reliably at temperatures up to 250°C, with a minimum bend radius of 1.6 mm.Constructed with a bare copper outer conductor and LD PTFE insulation, the RSR-031-LL ensures mechanical stability and thermal resilience. The cable's compact dimensions—0.787 mm outer diameter and 0.203 mm center conductor—make it ideal for dense system layouts. It is RoHS compliant and weighs only 0.26 kg per 100 meters, offering a lightweight solution without compromising durability.
ROSNOL’s microwave cable solutions are designed to meet the stringent demands of high-frequency transmission systems. Manufactured under ISO 9001-certified processes and fully compliant with RoHS and REACH standards, ROSNOL cables ensure consistent quality, reliability, and environmental safety. Custom cable configurations and engineering support are available to meet specific application requirements.
