8 GHz Ultimate-Protection Extreme-Voltage Ultra-Low-Loss Phase-Stable RF Cable W120

P/N: W120

  • Ultimate-protection cable for extreme power routing
  • 3000 V.DC structure for high-voltage systems
  • Ultra-low-loss path for 8 GHz transmission
  • Phase-stable routing for critical ECM systems
  • Built for naval and ground-based platforms
Engineering Note
The W120 is an 8 GHz ultimate-protection extreme-voltage ultra-low-loss phase-stable flexible RF coaxial cable designed for high-power microwave interconnects, electronic countermeasure systems, ground-based radar, naval radar, avionics systems, and extreme power routing where phase consistency, voltage withstand, low insertion loss, and large-diameter cable durability are required. Its 12.00 mm gray FEP ultimate-protection jacket provides a robust protective outer layer for demanding installations, 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–8 GHz operating capability, <750 PPM phase stability, 3000 V.DC dielectric withstand voltage, -155 dBc low PIM performance, >90 dB shielding effectiveness, and 31.0 dB/100m attenuation at 8 GHz for extreme-voltage phase-critical RF interconnect applications.
