Is there any way to optimize the IPD BALFHB-WL-01D3 to work at 865MHz at 22dbm for STM32WL55? And is there any hardware design guide for power of STM32WL like it is there Hardware design guide for STM32L0 application note AN4467.

Hello @SaiVenkat ,

Check the following ressources as guides for STM32WL, covering RF and power optimization:

  • AN5407: Optimized RF board layout for STM32WL Series
  • AN5457: RF matching network design guide for STM32WL Series
