Create lumped models from S-parameters

September 1, 2026 ยท View on GitHub

This is a collection of tools to convert S-parameters from RFIC EM simulation into a lumped model that can be used in all sorts of circuit simulation.

The code for all model extractions requires Python3 with the skitkit-rf library.
