World’s Best RF & Microwave Simulation Models
Passive Plus MVP

With over 30 years in the RF/Microwave industry, Passive Plus manufactures high quality, high power passive components using state-of-the-art manufacturing techniques.  Specializing in Magnetic & Non-Mag HI-Q capacitors and Power Resistive product lines, Passive Plus supplies reliable quality components to the aerospace, telecommunications, medical semiconductor, and military industries.

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.
