Hello, I'm a beginner in hardware design for STM32 MCU wireless. I usually get detailed information about component value recommendations in the datasheet or application note. But in STM32WL33, I get unclearer information than in other MCU wireless documentation like STM32WL5 or STM32WB55. Here is the application circuit from the STM32WL33 datasheet; there is no component value recommendation.
I have several question
1. what is L1 and L2 recomendation value?
2. I want to use this MCU for 433MHz or 868MHz, so what value recommendation for matching network components?
3. Why in the application circuit there is no RF switch? In AN5407 and MB1720 docs (STM32WL_QFN48_4Layers_Ref_Board) I found that using RF switch.
