18 GHz Mega-Size High-Voltage RF Precision Test Cable T80

P/N: T80

  • For high-power RF device testing
  • 2000 V.DC supports extreme voltage paths
  • 7.80 mm OD for mega-size routing
  • High-flex build resists heavy handling
  • Rated to 18 GHz for test benches
Engineering Note
The T80 is an 18 GHz mega-size high-voltage RF precision test cable designed for high-power device testing, EMC laboratory environments, large system-level test benches, and massive RF module interconnections where voltage handling, torsion resistance, bending durability, and low-loss transmission are key selection factors. Its construction uses a silver-plated copper inner conductor, low density PTFE dielectric, silver-plated copper strip inner shield, low density PTFE interlayer, silver-plated copper wire braiding, and a blue FEP jacket. The cable supports heavy-duty test routing while providing 82% velocity of propagation, >90 dB shielding effectiveness, 2000 V.DC dielectric withstand voltage, and operation up to 18 GHz.
