Free Tools and Models for RF & Microwave Design

The Modelithics SELECT library is a set of sample and free models. The library contains a selection of Global CLR™ models (capacitors, inductors and resistors) as well as some non-linear diode and transistor models.

I have been using Modelithics CLR libraries for several years, and have come to rely on them for all my simulation work. The models are accurate, scalable, and easy to use. A big benefit is that they save time. For example, the alternative to get accurate models is to use S-parameter measurement files. But this technique does not work with Monte Carlo, Yield, or Optimization. The scalable Modelithics models do support these analyses. The accuracy saves lab time; I find that the final values of circuit components, which results from lab testing, are almost always within one standard value of the simulation results. Gordon Mapes,
