T42KA/KB 40 GHz Armored RF Precision Test Cable

P/N: T42KA/KB

  • For 40 GHz VNA measurements
  • Armored structure resists crushing and torsion
  • Ultra-low VSWR supports signal purity
  • ±7° mechanical phase stability
  • ±0.05 dB amplitude stability under flexing
Engineering Note
The T42KA/KB is a 40 GHz armored RF precision test cable designed for rigorous VNA testing, high-precision instrument interconnects, EMC laboratory environments, system test benches, and on-site RF measurements where mechanical protection, phase repeatability, low reflection, and signal integrity are key selection factors. Its armored construction combines a T42 FEP-jacket core, silver-plated copper armor, and a purple PTFE outer jacket, providing crush resistance, torsion resistance, and protection against pulling and severe laboratory handling. The cable supports high-precision measurements with VSWR ≤1.30 @40GHz, ±7° mechanical phase stability, ±0.05 dB amplitude stability, >90 dB shielding effectiveness, and operation up to 40 GHz.
