Modelithics Virginia Diodes MVP Model Listing

VDI manufactures state-of-the-art test and measurement equipment for mm-wave and THz applications. These products include Vector Network Analyzer, Spectrum Analyzer and Signal Generator Extension Modules that extend the capability of high performance microwave measurement tools to higher frequencies. VDI's component products include detectors, mixers, frequency multipliers and custom systems for reliable operation at frequencies between 50 GHz and 3 THz.

Start your next design with the most accurate and well documented models in the industry! Our passive and active model libraries contain up-to-date, measurement-based models that are fully integrated with the latest electronic design automation (EDA) simulation tools. Our goal is to help you achieve your design goals and make part selection and design optimization decisions more quickly and with more confidence.

Modelithics high accuracy measurement-based models reliably track how component performance will change with various input parameters over a specified frequency range documented in a model information data sheet for each component. Please visit our products page for more information about available models and the unique advantages of using Modelithics model libraries.
