3D Unilateral Transducer Gain & Group Delays & Quality FactorsģD Space surrounding the chart is used to plot power gains too. Circles which are never closed on the Smith chart get together in the South hemisphere. Unconditionally stable: south hemisphere.

Works for all active & passive microwave circuits, even with negative resistance! South hemisphere for negative resistance, North hemisphere for positive resistance, East inductive, West capacitive Amplifier Stability Circles

Key Features of the 3D Smith Chart Active & Passive Circuits 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 tool is an educational tool for easy and fast understanding and use of both 2D and 3D Smith charts in Z/Y configurations when using resistances, capacitors, inductors, in series or shunt configuration, transmission lines or stubs. Since its invention in the early to mid 20th Century the Smith Chart has been a 2D tool that can be printed out on paper and used to display multiple parameters like impedances, admittances, reflection coefficients etc. The Smith chart is fundamental tool used by RF engineers to assist in solving problems with transmission lines and matching circuits. Click here to learn more about the 3D Smith Chart. The improved tool now enables, full 3D visualization, intuitive user interface, easy installation as well as state of the art concepts.

The 3D Smith Chart tool, meant to help understand and use both the 2D Smith chart and the 3D Smith chart, has now been made available free of cost for all undergraduate, masters and PhD students.
