Engineering Note
The W83 is an 18 GHz maximum-protection ultra-low-loss high-voltage phase-stable flexible RF coaxial cable designed for precision microwave interconnects, avionics routing, phased array radar, ECM systems, and high-power aerospace RF assemblies where phase consistency, ultra-low loss, voltage withstand, and environmental protection are required. Its 8.30 mm gray FEP maximum-protection jacket provides a large-diameter protective outer layer for demanding environments, while the LD PTFE dielectric, silver-plated copper inner conductor, silver-plated copper strip inner shield, and silver-plated copper braid outer shield support stable microwave signal transmission. The cable combines DC–18 GHz operating capability, <750 PPM phase stability, 2500 V.DC dielectric withstand voltage, -155 dBc low PIM performance, >90 dB shielding effectiveness, and 60.6 dB/100m attenuation at 18 GHz for ultra-low-loss phase-critical RF interconnect applications.
