26.5 GHz Ruggedized Economy RF Precision Test Cable J52

P/N: J52

  • For high-power ATE test systems
  • 500 V.DC supports higher-voltage benches
  • PUR jacket resists workshop abrasion
  • Linear phase supports fast compensation
  • Rated to 26.5 GHz for test links
Engineering Note
The J52 is a 26.5 GHz ruggedized economy RF precision test cable designed for heavy-duty automated test equipment, high-volume production lines, and higher-voltage RF test benches. 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 blue PUR wear-resistant jacket. The cable supports frequent production-line handling while providing 76% velocity of propagation, >90 dB shielding effectiveness, 500 V.DC dielectric withstand voltage, and ±0.3°/GHz mechanical stationary phase for economical 26.5 GHz test links.
