A π-type matching network is essential for antenna matching in the circuit design. CLC structure is recommended for the matching network. 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.) some fun tonight facebook
