26.5 GHz Heavy-Duty High-Voltage RF Precision Test Cable T50

P/N: T50

  • For continuous high-volume RF testing
  • 2000 V.DC supports high-voltage benches
  • 600,000 bending cycles for durability
  • Heavy-duty 5.10 mm test construction
  • Rated to 26.5 GHz for lab links
Engineering Note
The T50 is a 26.5 GHz heavy-duty high-voltage RF precision test cable designed for continuous laboratory measurements, EMC lab environments, system-level test benches, and high-volume RF testing where voltage handling, bending durability, signal integrity, and long service life 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 long-lasting test routing while providing 82% velocity of propagation, >90 dB shielding effectiveness, 2000 V.DC dielectric withstand voltage, 600,000 bending cycles, and operation up to 26.5 GHz.
