Vector Network Analyzer Extension Modules

VDI’s VNA Extenders provide high performance frequency extension of vector network analyzers into the THz range. Models are currently available for coverage from 50GHz to 1,100GHz, with additional bands under development. These modules combine high test port power and superb dynamic range to offer unparalleled performance. VDI’s VNA Extension Modules are compatible with all modern network analyzers, and have been integrated with a variety of probe stations for on-wafer testing. Also, Dominion MicroProbes has recently developed on-wafer test probes for >500GHz that are compatible with VDI’s VNA Extenders. When used in conjunction with VDI’s PM4 power meter, power leveling and sweeping are possible. Available options include increased test port power (selected bands), micrometer driven attenuators, reduced input frequency (24GHz or 20GHz), increased cable length and waveguide based calibration kits.  Contact VDI to discuss VNA Extender configurations that will yield the best performance for your application.
