Junkosha Microwave/mmWave Coaxial Cable Assembly
Junkosha’s metrology-grade cable exhibits excellent phase (within +/- 4.5˚ at 50GHz) and amplitude (within +/- 0.08dB at 50GHz) stability in flexure alongside strong phase stability in temperature. The cable is flexible and can maintain this level of performance when bent 180˚ on a 2.25” radius mandrel, with no spring back. Able to reach 50GHz and available in a 2.4mm connector, the assembly also displays impressive performance durability – 50,000 tick tock cycles is typical. The ruggedized port side NMD connector is also available to ensure reliable connections to the Vector Network Analyzer (VNA).
