Dr. Andrei Muller, progenitor of the world's first 3D Smith Chart™ software program, has teamed with a handful of able colleagues to release a commercial version of this paradigm-changing design and analysis tool. The following press release was issued on July 17, 2019.

Example of one of these new features showing a 3D frequency sweep representation over S11. The paths of the 2 nH inductor and −2 pF capacitor represented between 1 and 3 GHz.

3D Smith Chart representation for the shunt inductance and quality factor for different inductors within 1-16 GHz. As the inductance becomes negative it enters the 3D Smith Chart interior. The quality factor is represented as a generalized cylinder for each frequency point around the corresponding inductance

Many New Features Added

3D Smith Chart™ announces a new version (1.02) of the 3D Smith Chart with new features. The original 3D Smith Chart tool (version 1.01) extended 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 1 by mapping them as arcs on the 3D sphere. The South represents active areas with negative resistance, North areas represent passive with positive resistance, East inductive, and West capacitive. (North Pole: perfect match, South Pole infinite mismatch).

Now, based on the preprint article entitled "Reconfigurable radiofrequency electronic functions designed with 3D Smith Charts in Metal-Insulator-Transition Materials," several new features have been added to the 3D Smith Chart version 1.02, Windows 64-bit compatible tool. The new features include:

  • 3D frequency (live) sweeping representation (for visualizing the dynamics of the S parameters variation). For example, negative capacitances & positive inductances can be directly distinguished due to their opposed frequency sweeping orientation. Furthermore, no uncertainty on the sweeping range start & end points occurs now while interpreting the results.
  • Unique inductor quality factor visualization over the S11 parameters in 3D, 3D inductance display over the S11 parameter and Q as a generalized cylinder of a radius corresponding to its normalized value for each frequency point. Different models of definitions are used (shunt inductor model, series inductor model).
  • Several improvements in terms of rendering/visualizations, helpful both in actual design and learning the 2D Smith and 3D Smith Chart concepts (axes system, "Greenwich" constant resistance meridian, surface transparency, etc.).

The tool is well suited for amplifier stability analysis, oscillator design, filters and group delay analysis. Visit www.3dsmithchart.com for more information and for ordering: http://3dsmithchart.com/#quote

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
