110 GHz Ultra-Thin Phase-Stable Low-Loss RF Cable W15

Engineering Note

The W15 is a 110 GHz ultra-thin phase-stable low-loss flexible RF coaxial cable designed for precision microwave interconnects, avionics routing, phased array radar, ECM systems, and high-frequency RF assemblies where phase consistency and compact cable routing are critical. Its 1.50 mm gray PFA jacket, LD PTFE dielectric, silver-plated copper inner conductor, silver-plated copper strip inner shield, and silver-plated copper braid outer shield support stable signal transmission in demanding microwave environments. The cable combines DC–110 GHz operating capability, <1000 PPM phase stability, >90 dB shielding effectiveness, and a lightweight ultra-thin structure for space-limited high-frequency interconnect applications.
