Lumped 2-Element Z-Y Matching Networks

The templates in the Lumped 2-Element Z-Y Matching Networks are for synthesizing an arbitrary impedance or admittance, or for matching to a device's equivalent circuit that is modeled as an R-C or R-L network. The matching networks use only lumped, ideal elements, and the impedance match is only for a single frequency, so the capabilities of these templates are rather limited. You might wish to use the Passive Circuit DesignGuide for impedance matching.
