Mastering the Smith chart is essential to entering the world of RF and microwave circuit design as all practitioners use this as if it is well understood by others. Additionally since 2019 it includes frequency visualization too within the 3D space-spotting the clockwise and counter clockwise dependencies as frequency sweeps in real-time. The Smith chart is a powerful graphical tool used in the design of microwave circuits.

(North pole: perfect match, South pole infinite mismatch). The South-represents active areas with negative resistance, North areas represent passive with positive resistance, East inductive and West capacitive. The 3D Smith chart tool extends the Smith chart capabilities for the first time since the 1939s to make it usable for circuits with negative resistance based on a unit sphere that plots circuits with reflection coefficient magnitudes larger than one by mapping them as arcs on the 3D sphere. In this video, i have explained Smith Chart Example with following outlines.0. The simultaneous display of a variety of parameters form imported touchstone files speeds up the analysis phase and helps in the optimizations of the high frequency devices. The tool also has an advanced analysis mode for S-parameters, stability circles, power levels, group delays and quality factors making it a new software for the measuring stage or design stage of microwave devices. The 3D Smith chart is an ideal educational tool for the fast and simple understanding and matching use of both 2D and 3D Smith charts in both Z/Y configurations when using resistances, capacitors, inductors, in series or shunt configuration, transmission lines or stubs.

The 3D Smith chart tool, that enables the understanding and use of both 2D Smith chart and 3D Smith chart, is now available for free for all undergraduate, master and PhD students.
