Modelithics and Qorvo to Expand the GaN RF Simulation Model Library

Modelithics, Inc. of Tampa, Florida and Qorvo of Richardson, Texas reportedly plan to expand the Modelithics™ Qorvo GaN Library of high accuracy non-linear models for Qorvo transistors. While the current GaN library version (v1.5) has 29 packaged and die transistor models, the companies will add over 20 new Qorvo GaN transistor models.

“This collaboration has allowed Modelithics to apply its many years of experience with model library software development to the benefit of Qorvo customers. Qorvo’s sponsorship of free distribution and support has enabled this high accuracy non-linear library to be quickly embraced and widely utilized by the international PA design community,” said Modelithics president and CEO Larry Dunleavy.

The non-linear GaN models offer temperature scaling, self-heat scaling factor parameter, intrinsic I-V sensing capability, bias dependence, and measurement validations including load pull and pulsed IV. Each model has a model datasheet gives detailed information about the model features, model development, model performance plots, and parameter settings.

Qorvo approved customers can request the company’s GaN Library that is available for free through the Modelithics website (, then click on Qorvo logo).
