Thanks for the really quick reply! So, is that what the pi matching network is for, in the reference design of the datasheet? That does the matching, and the output impedance is immediately 50 ohms? Thanks.

Hi fellow ESP32ers, The ESP32-S3-PICO-1 datasheet never states the RF output impedance, unlike other 'pico' variants of ESP32 chips. I was told that it was not 35 + j0 ohms nor 50 ohms, and that I needed to measure it myself. As you can imagine, I'm a beginner who doesn't have access to the kind of ...
