26.5 GHz 141 Low-Loss Semi-Rigid RF Coaxial Cable G36

P/N: G36

  • For high-power RF module routing
  • Optimized PTFE supports lower attenuation
  • 1000 V.DC for higher voltage handling
  • Seamless copper tube provides high shielding
  • Rated to 26.5 GHz for internal links
Engineering Note
The G36 is a 26.5 GHz low-loss semi-rigid coaxial cable designed for high-power internal RF routing where voltage handling, shielding, shape retention, 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 stable microwave interconnects in RF modules, phased array radar systems, avionics, and precision instruments. The cable provides 76% velocity of propagation, >165 dB shielding effectiveness, 1000 V.DC dielectric withstand voltage, and operation up to 26.5 GHz.
