The 50 Ω Question: Impedance Matching in RF Design

Witryna10 gru 2024 · The output impedance of the RF pins of ESP32 (QFN 6x6) and ESP32 (QFN 5x5) are (30+j10) Ω and (35+j10) Ω, respectively. 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.)
