Modelithics, Inc Logo
World’s Best RF & Microwave Simulation Models
High Frequency Electronoics MVP

Our target audience includes engineers, managers, educators and other technical personnel involved in the design and development of products and technologies at high frequencies and high speeds. Our coverage of this area of engineering includes all possible applications, which can change rapidly as new, creative ideas are developed into products

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.
