360B/37XXXA/B Series Vector Network Analyzers

On-wafer measurements are becoming increasingly important in the microwave industry. Modern MMIC designs have opened the way to cost reduction and industry expansion in both military and commercial applications. The Anritsu 360B and 37XXXA/B series Vector Network Analyzers are used to make accurate, high-speed on-wafer measurements in both R&D and production environments. Rather than relying on models based upon low frequency measurements, the 360B VNA permits actual measurement of MMIC performance and accurate characterization of active and passive on-wafer components to 110 GHz. This application note addresses the specifics of such applications and how the Anritsu VNAs may be used to obtain accurate measurement results. The V Connector® (1.85 mm) was developed as an extension of the industry standard 40 GHz K Connector® (2.9 mm). The V Connector exhibits mode-free operation to 67 GHz. It is assembled using procedures that are similar to those used on K Connectors. V085 semirigid coaxial cable is manufactured using microporous Teflon to provide a low loss, phase stable cable for test applications.
