18 GHz 250 Low-Loss Semi-Rigid RF Coaxial Cable G64

P/N: G64

  • For high-power RF chassis routing
  • 2200 V.DC supports extreme voltage paths
  • 6.35 mm OD for large power links
  • Seamless copper tube provides high shielding
  • Rated to 18 GHz for internal systems
Engineering Note
The G64 is a large-size 18 GHz low-loss semi-rigid coaxial cable designed for high-power internal RF routing where voltage handling, shielding, stable cable forming, and elevated temperature capability are important. Its construction uses a silver-plated copper inner conductor, optimized PTFE dielectric, and seamless copper tube outer shield, supporting permanent microwave interconnects in broadcasting equipment, radar systems, naval and ground platforms, avionics, and defense RF chassis. The uploaded datasheet contains conflicting second-page data, so the specifications below include only G64 values confirmed on page 1.
