P/N: T80KA/KB
- For high-power 18 GHz VNA testing
- 2000 V.DC supports high-voltage benches
- 10.40 mm armor protects heavy-duty links
- ±3° mechanical phase stability
- ≤1.25 VSWR supports clean measurements
Engineering Note
The T80KA/KB is an 18 GHz high-voltage armored RF precision test cable designed for high-power VNA testing, EMC laboratory environments, large system-level test benches, and on-site RF measurements where voltage handling, mechanical protection, phase repeatability, and heavy-duty signal routing are key selection factors. Its armored construction combines a T80 FEP-jacket core, silver-plated copper armor, and a 10.40 mm 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 @18GHz, ±3° mechanical phase stability, ±0.05 dB amplitude stability, 2000 V.DC dielectric withstand voltage, >90 dB shielding effectiveness, and operation up to 18 GHz.
