26.5 GHz Economy RF Precision Test Cable J50

P/N: J50

  • For high-volume ATE test systems
  • Transparent FEP supports visual inspection
  • Linear phase supports fast compensation
  • Flexible construction for frequent handling
  • Rated to 26.5 GHz for test links
Engineering Note
The J50 is a 26.5 GHz economy RF precision test cable designed for automated test equipment, high-volume production lines, and repeatable microwave component verification. Its construction uses a silver-plated copper inner conductor, low density PTFE dielectric, silver-plated copper strip inner shield, PTFE interlayer, silver-plated copper wire braiding, and a transparent FEP jacket. The cable supports frequent test-system handling while providing 76% velocity of propagation, >90 dB shielding effectiveness, and ±0.3°/GHz mechanical stationary phase for economical 26.5 GHz test links.
