The 8 Series from Junkosha are mmWave Coaxial Cable Assemblies that operate up to 50 GHz. These VNA test assemblies exhibit phase stability of ± 4.5° and amplitude stability of ± 0.08 dB at 50 GHz in flexure alongside strong phase stability with temperature variations. They have an insertion loss of less than 6.2 dB and a VSWR of 1.43:1. These metrology-grade cable assemblies have a shielding effectiveness of more than 90 dB and a nominal propagation velocity of 79%. They can be bent 180° and have a 2.25-inch radius mandrel with no spring back. These cable assemblies also deliver impressive performance durability, surpassing 50,000 tick-tock cycles during testing. They are available with a ruggedized port-side NMD connectors to ensure reliable connections to a VNA. These cable assemblies are ideal for VNA, calibration, and accuracy measurement applications.
