Description

scikit-rf (aka skrf) is an Open Source, BSD-licensed package for RF/Microwave engineering implemented in the Python programming language. It provides a modern, object-oriented library for network analysis and calibration which is both flexible and scalable. See some of the features below and check out the Documentation for a more in-depth look at scikit-rf.

Getting Started

Plot touchstone data on a smith chart, in 3 lines.

import skrf as rf
ntwk = rf.Network('ring slot.s2p')
ntwk.plot_s_smith()

For more information, tutorials, and

examples, see the Documentation
