45. Coil: Matching circuits - fahsuanlin/labmanual GitHub Wiki

Here are values for inductors and capacitors in a Pi impedance matching network. We consider that the loading causes only a resistive loading. The reactive part of the loading can be first compensated by adding a capacitor or an inductor in series.
