I'm designing a PCB that uses a ESP32-D0WD-V3 QFN 5x5 and I want to have a uFL port for 2.4Ghz Wifi/BLE. Directly from the datasheet, I get the following note:
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.
Following the datasheet, I went into https://www.omnicalculator.com/other/impedance-matching and filled the blanks like so:
Results of the calculator
I have no experience with RF design or impedance matching. Can someone advise if my steps are correct and give some pointers into what can I improve?
