18 GHz Standard Semi-Rigid Coaxial Cable G64E

P/N: G64E

  • For heavy-duty RF chassis routing
  • 6.35 mm OD supports large cable paths
  • Seamless copper tube provides high shielding
  • Solid PTFE for cost-effective signal paths
  • Rated to 18 GHz for high-power links
Engineering Note
The G64E is an 18 GHz standard semi-rigid coaxial cable designed for heavy-duty internal RF routing where power capacity, shielding, permanent cable forming, and mechanical stability are key selection factors. Its construction uses a silver-plated copper inner conductor, solid PTFE dielectric, and seamless copper tube outer shield, supporting high-power broadcasting modules, radar chassis links, heavy-duty microwave component interconnects, and large-scale RF chassis setups. The 6.350 mm OD construction provides a robust standard semi-rigid cable path for large internal RF systems.

Target Applications

High-Power Broadcasting Modules
Suitable for permanent internal routing where large cable diameter, high shielding, and heavy-duty structure are required.
Heavy-Duty RF Module Interconnects
Supports large microwave component interconnections where robust semi-rigid structure is more important than compact cable diameter.
Radar and Large Chassis Links
Used in phased array radar, large RF chassis setups, and general heavy-duty internal cable paths operating up to 18 GHz.
