Hi All,
When dealing with RF transmitters, it's common advice to always put a load on a transmitter before turning it on, because running it with no load can break it. I'm curious if that applies to STM32WL microcontrollers as well. If I transmitted a wireless packet and accidentally left the RFO_HP pin disconnected (open termination), will that damage the microcontroller? Or does it have some way of protecting itself? Does damage only occur if you output above a certain power level?
I read the errata and learned about the TxClampConfig register. I'm curious if that comes into play at all.
