The Qorvo GaN transistor model library contains a powerful collection of high-accuracy nonlinear simulation models for die- and package-format GaN transistors from Qorvo. Each model has advanced design features including variable bias, temperature scaling, self-heating effects, intrinsic I-V sensing, and bondwire settings when applicable. The Modelithics Qorvo GaN library also contains example projects that demonstrate the model features and facilitate the process of test bench setup for common linear and nonlinear design simulations.
Modelithics has used select models to generate power amplifier reference designs. They have then fabricated, tested and documented these designs to illustrate the model accuracy and usefulness for design application, as well as the individual GaN device capabilities at the PA circuit level. One reference design for a 1.8-2.2 GHz PA design illustrates how the use of intrinsic port access and multiharmonic tuning features of the GaN models, and the use of Modelithics Microwave Global Models™ for the passives, were keys to first-pass design success.
