Engineering Note
The W75 is an 18 GHz maximum-protection extreme high-voltage phase-stable low-loss flexible RF coaxial cable designed for precision microwave interconnects, avionics routing, phased array radar, ECM systems, and high-power RF assemblies where phase consistency, extreme voltage withstand, low PIM behavior, and robust jacket protection are required. Its 7.40 mm gray PFA jacket provides a heavy-duty 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 an extended -55 °C to +165 °C temperature range for protected phase-critical high-voltage RF interconnect applications.
