Matching Network Calculator
See our other Electronics Calculators.
The following is a design tool which calculates the values for an L matching network.
The Q (bandwidth) of a filter is fixed for an L matching network, because it is set by the ratio of the source and load resistance which are typically fixed values. For a variable Q use a Pi or T matching network.
This calculator allows for complex source and load impedances, or purely resistive impedances. You can enter in capacitive or inductive components to the load and source reactance, but not both. For example, if the load is capacitive, then enter in a value for the load capacitor, but not the inductor value.
