Engineering Note
The T50KA/KB is a 26.5 GHz high-voltage armored RF precision test cable designed for high-power VNA testing, EMC laboratory environments, system-level test benches, and on-site RF measurements where voltage handling, mechanical protection, phase repeatability, and signal integrity are key selection factors. Its armored construction combines a T50 FEP-jacket core, silver-plated copper armor, and a purple PTFE outer jacket, providing crush resistance, torsion resistance, and protection against severe laboratory handling. The cable supports high-reliability measurements with VSWR ≤1.25 @26.5GHz, ±5° mechanical phase stability, ±0.05 dB amplitude stability, 2000 V.DC dielectric withstand voltage, >90 dB shielding effectiveness, and operation up to 26.5 GHz.
