VNA-Grade Phase-Stable RF Test Cable Assemblies – VC Series
VNA-Grade Phase-Stable RF Test Cable Assemblies for Precision Measurement
The VC Series VNA-Grade Phase-Stable RF Test Cable Assemblies are designed for the most demanding calibration and vector network analyzer (VNA) measurement environments. Covering frequencies up to 110 GHz, these assemblies deliver exceptional phase stability, amplitude repeatability, and low insertion loss required for metrology-level test accuracy and long-term measurement consistency.
Exceptional Electrical Stability and Repeatability
Each VC Series cable maintains phase stability typically within ±1° to ±5° during flexure and amplitude stability better than ±0.05 dB across repeated bend cycles. Optimized for VNA port extensions and calibration setups, these assemblies combine low VSWR (≤ 1.20) with minimal insertion loss, ensuring accurate S-parameter characterization even in the highest frequency bands. Their excellent return loss and shielding effectiveness (≈100 dB) guarantee signal integrity in sensitive test environments.
Ruggedized Construction for Metrology and Calibration Labs
Built to withstand thousands of flex cycles, the VC Series RF Test Cables feature precision stainless-steel connectors, reinforced PTFE or FEP dielectric structures, and a high-density braid that minimizes mechanical drift. With reliable operation from −55 °C to +165 °C and robust strain-relief design, these assemblies provide long-term mechanical and electrical repeatability in both laboratory and production test applications.
Compliance and Customization Options
All VC Series RF Test Cable Assemblies are produced in full compliance with REACH and RoHS standards. Mechanc offers complete customization capability, including non-standard lengths, right-angle or bulkhead connectors, optional armor or strain-relief enhancements, and tailored connector pairings to meet specific VNA calibration and test fixture requirements.
