Junkosha Microwave/mmWave Coaxial Cable Assembly
Junkosha’s new mmWave VNA Test Cable Assembly exhibits excellent phase (within +/- 4.5˚ at 50 GHz), and amplitude (within +/- 0.08 dB at 50 GHz) stability in flexure alongside strong phase stability in temperature through its 50 GHz bandwidth, available with NMD connector.
The assembly also displays impressive performance durability, surpassing 40,000 tick tock cycles during testing. The cable is bent 180˚ on a 2.25” radius mandrel with ease, demonstrating superior flexibility and no spring back. A ruggedized port side NMD connector is also available to ensure reliable connections to the VNA.
