WitrynaDefinition Impedance matching is designing source and load impedances to minimize signal reflection or maximize power transfer. In DC circuits, the source and load should be equal. In AC circuits, the source should either equal the load or the complex conjugate of the load, depending on the goal. 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.
