3D Smith Chart
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
Unconditionally stable: south hemisphere.
Infinity becomes compact.
Circles which are never closed on the Smith chart get together in the South hemisphere.
3D Space surrounding the chart is used to plot power gains too. Can be displayed over the constant gain circles which are on the surface.
Match circuits on 5 constant resistance, reactance, conductance, susceptance and constant reflection coefficient’s magnitude circles.
Choose from the 5 paths (r,x,g,b,lat) and add normalized r,x,g,b, /stubs equivalents or lossless transmission lines
Any s1p and s2p files can be imported (touchstone format).
Parameters are plot on both 2D& 3D Smith charts in Z/Y reconfigurable format.
The tool proposes a dynamic frequency sweep to tune live the device under study.
The ports have complex characteristic impedances too. The tool can deal with voltage reflection coefficient / power wave.
The 3D Smith chart tool is a ( completely reconfigurable) ,very easy to install software operating in Windows and programmed in Java for high frequency engineering.
The tool contains two modes: analysis mode ( S parameters touchstone files based) and design mode- both including a 2Dand 3D Smith charts in Z/Y( impedance/ admittance versions)
See the documentation for a very detailed overview of the tool
It uses a new vision in microwave analysis and design.
