Impedance matching circuits
Witryna7 kwi 2024 · To this end, we first need to define the nodal quality factor that is obtained from the equivalent impedance or admittance of different nodes of the matching circuit. If the equivalent impedance of a node is Z = R + jX, the node quality factor is defined as: Qn = X R Q n = X R Equation 2. Witryna24 kwi 2024 · In every L filter, there is only one combination of L and C that can match a given input impedance to given output impedance. For example, to match a 50 Ω load to a 100 Ω load at 14MHz, we need a 560nH inductor with a 114pF capacitor – this is the only combination that can do matching at this frequency with these resistances.

WitrynaThis means that our impedance-matched circuit looks like this: To evaluate the efficacy of the matching network, we can run a simulation and then plot the voltage across the load divided by the current flowing into the load, which is equal to the input impedance. (In this case the current flowing into the load is the current through inductor L1.)
