    3D Smith Chart

    A new vision in microwave analysis and design.

Active & Passive Circuits

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

Unconditionally stable: south hemisphere.
Infinity becomes compact.
Circles which are never closed on the Smith chart get together in the South hemisphere.

3D Unilateral transducer gain & group delays & quality factors.

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.

2D & 3D mode, Z-Y Smith charts

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

S parameters

Any s1p and s2p files can be imported (touchstone format).
Parameters are plot on both 2D& 3D Smith charts in Z/Y reconfigurable format.
* New 3D frequency sweeping - orientation visualization
* New inductance and quality factors visualization in 3D

Dynamic frequency sweep & complex ports

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

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 2D and 3D Smith charts in Z/Y (impedance/ admittance versions)

See the documentation for a very detailed overview of the tool
For features added in update 1.02 see this documentation

See these slides for a quick overview, also available in Spanish, Italian and Chinese

For an overview of the new features in version 1.02 please see this video and the press release
