Engineering Note
The L52 is a 26.5 GHz low-loss flexible RF coaxial cable designed for higher-power microwave routing, base station interconnections, RF device testing, and system-level RF assemblies where low attenuation, low PIM behavior, and reliable shielding are required. Its 5.20 mm blue FEP jacket, LD PTFE dielectric, silver-plated copper strip inner shield, and silver-plated copper wire braid outer shield support stable signal transmission in demanding microwave environments. The cable combines DC–26.5 GHz operating capability, -155 dBc low PIM performance, 1000 V.DC dielectric withstand voltage, and robust average power handling for cost-effective high-power RF interconnect applications.
