This program demonstrates how to use a Smith-chart to solve impedance matching problems.
Instead of drawing on the Smith-chart and doing the mathematics involved with a calculator, you just click with the mouse button on the spot where you want your lines to end and the program calculates the proper capacitance or inductance.
This program can be a good start to learn working with a Smith-chart.
The instructions and examples can be found in the Manual (a pdf-file).

Om December 10, 2011 I have released a new version of Pasan: Pasan 3.2
This version has many improvements and also contains open shunt stubs.
Version 3.2 contained a small bug, so on December 17, 2011 I released version 3.3
