• Smith Chart Software - SimSmith is a highly interactive, real time Smith chart graphing program. Circuits are constructed using drag-n-drop. Load files can be imported from the EZNEC and CocoaNEC antenna simulation software and from the AIM4170 and miniVNApro antenna analyzers. Circuits and load files can be of any size. Key Features: SimSmith is one of the few Smith chart packages which models transmission line losses. SimSmith also allows the description of circuit elements using algebraic equations. SimSmith has only one screen and allows the screen to be resized to increase workspace or readability.

• Zplots - Impedance Plots with MS Excel Charts - Zplots is an Excel application that allows you to plot impedance and related data obtained from a variety of sources. You can plot on both an XY chart and a Smith chart as well as view the data in tabular format. The XY chart can be customized with your choice of trace lines. Frequency (in MHz) is always shown on the X axis.

• Interactive Smith chart - The interactive Smith chart enables users to navigate their way around a Smith chart, using simple discrete element impedance matching. This page allows users to try using the Smith chart, for education and interest purposes, without installing any software. Try changing the value in the load box to see the location of the impedance on the chart.

• Smith chart calculator - linSmith is a Smith Charting program, mainly designed for educational use. It allows defining multiple load impedances (different frequencies), and adding components (discrete components and line sections) in series and parallel. It plots the impedances on the screen, shows the values in table format, and is able to generate publication quality Postscript output.

• RevLoad - This graphics-intensive program reveals the load on the output of a matching-network, based on measurements of the components in that network. Adjust the network (tuner) for a flat input, measure or look up the network component values and you will immmediately see the R and jX values of the load on the network, presented as both a schematic with the component values and as a Smith Chart normalized to the specified system impedance.

• SNASharp - SNASharp is a free software application designed to work with scalar network analyzers compatible with NWT software from DL4JAL. It is used to measure and analyze the scattering parameters (S-parameters) of microwave devices. Provide several measurements and analysis tools including Smith chart, Polar plot, S-parameter tables, Transmission line calculator
