Engineering Note
The S50 is a 26.5 GHz cost-effective flexible low-loss RF coaxial cable designed for RF testing, wireless communication base station routing, avionics interconnects, and high-density microwave systems where low loss, low PIM behavior, flexible routing, and price-performance balance are required. Its 5.20 mm blue FEP jacket, LD PTFE dielectric, silver-plated copper inner conductor, silver-plated copper strip inner shield, and silver-plated copper braid outer shield support reliable high-frequency signal transmission in compact RF assemblies. The cable combines DC–26.5 GHz operating capability, -155 dBc low PIM performance, 1000 V.DC dielectric withstand voltage, >90 dB shielding effectiveness, and a 26 mm static bending radius for cost-effective flexible low-loss RF interconnect applications.
