50 GHz High-Temperature Phase-Stable Low-Loss RF Cable W30

P/N: W30

  • High-temperature cable for harsh RF systems
  • Phase-stable path for precision microwave routing
  • Low-loss structure for 50 GHz interconnects
  • Low PIM design for cleaner signals
  • Built for radar and avionics assemblies
Engineering Note
The W30 is a 50 GHz high-temperature 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, low loss, and extended temperature capability are required. Its 3.10 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–50 GHz operating capability, <750 PPM phase stability, -155 dBc low PIM performance, >90 dB shielding effectiveness, and an extended -55 °C to +165 °C temperature range for phase-critical RF interconnect applications.
