Pasternack, a leading provider of RF, microwave and millimeter wave products, releases of an all new line of ruggedized phase stable VNA test cables operating up to 40 GHz, depending on the series. These VNA test cables are specially designed to withstand the rigors of test lab use and production testing for 50 ohm communications systems.
The new phase stable cables can be ordered with male or female versions of SMA or Type-N connectors for cables operating to 18 GHz, 2.92 mm connectors for cables operating to 26.5 GHz or 2.4 mm connectors for test cables performing up to 40 GHz. Torsion resistant connector heads are directly attached to stainless steel conduit style armoring, providing a rugged design for up to 5,000 mating cycles with proper care. The cable’s armoring enhances amplitude and phase stability by preventing stress due to over bending while maintaining the flexibility required for testing in a lab environment.
Pasternack’s new VNA test cables have a maximum phase change of ± 2 degrees at 18 GHz, ± 3 degrees at 26.5 GHz and ± 5 degrees at 40 GHz with typical calibration procedures. Minimal phase change is essential because amplitude and phase variation, following VNA calibration, can cause inaccurate S Parameter measurements. As a result, amplitude and phase stable cables are needed to make accurate Vector Network Analyzer measurements. Pasternack’s new amplitude and phase stable ruggedized VNA test cables provide the reliable, repeatable and accurate test results users require.
