Virginia Diodes Inc. introduced new mini vector network analyzer extension modules, with one quarter of the volume of earlier models. These smaller modules are reduced in size but yield the same industry leading performance as the original designs. This makes them extremely attractive for applications such as probe stations and antenna ranges.

This smaller footprint is enabled by a more efficient, simplified power supply and the resultant elimination of cooling fans. These modules combine high-test port power with exceptional dynamic range and unmatched stability. VDI's VNA Extenders provide high performance frequency extension of vector network analyzers from 50 GHz - 1.1 THz. Mini-modules are currently available for WR15, WR12, and WR10, with higher frequency bands coming soon. Detailed specifications for all VNA extension modules can be found at
