Engineering Note
The W50 is a 26.5 GHz heavy-duty high-voltage phase-stable low-loss flexible RF coaxial cable designed for precision microwave interconnects, avionics routing, phased array radar, ECM systems, and rugged RF assemblies where phase consistency, voltage withstand, and jacket protection are required. Its 5.20 mm gray FEP heavy-duty jacket provides superior environmental protection, 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–26.5 GHz operating capability, <750 PPM phase stability, 1500 V.DC dielectric withstand voltage, >90 dB shielding effectiveness, and an extended -55 °C to +165 °C temperature range for protected phase-critical RF interconnect applications.
