VNA Test Cables
FlexiRF’S VNA test cable assembly series is designed to provide customers with repeatable and precise vector network analyzer (VNA) measurement values.
In the testing scenarios of Vector Network Analyzers (VNAs), the vulnerability of precision coaxial inteRFaces has long been an industry challenge.
Description
Product introduction
FlexiRF's VNA test cable assemblies are engineered to deliver consistent, accurate measurement results for Vector Network Analyzers (VNAs), addressing a longstanding industry pain point: the fragility of precision coaxial interfaces. Traditional test cables often suffer from wear, structural deformation, or electrical performance degradation in inner conductors and dielectric supports due to frequent plugging/unplugging, bending, or mechanical stress-issues that compromise test reliability and risk equipment failure. Our cables solve this with innovative design and robust construction.
Product Structure Features
Classified by operating frequency, the product lineup includes three key series:
26.5GHz 3.5mm interface cable assemblies
40GHz 2.4mm cable assemblies
67GHz 1.85mm NMD cable assemblies

Important Notes
1. For custom length cable assemblies, please don't forget to leave your length info on the checkout page;
2. All the cable assemblies can be provided with phase-matched pairs or groups; If you need the cables to be phase matched,please send email to us: sales@flexirf.com
