If you are unsure what the reactance is set it to zero for a first pass approximation. The inputs ask for source resistance and source reactance. There is one menu item to select if there is to be any DC current or not, that also affects the topology. For example in some topologies there may be 2 inductors and one capacitor and in a different configuration it may be 2 capacitors and one inductor.

The circuit topology can change depending on the inputs. There are some important items to understand when using this tool. This calculator will give you the circuit topology as well as the component values. This technique doesn’t work for wide band requirements, but is a simple way to achieve this at a specific frequency.

This tool will help you create a matching circuit so that optimal power transfer occurs between unmatched loads. The Pi match circuit gets its name because the circuit topology can look like a pi symbol.
