Hi, I want to use BALFHB-WL-05D3 balun with STM32WL MCU. Datasheet give a PCB layout recommendation but no schematic. In this layout, there are components between RFO_IN and TX output of the MCU, which one ? Also, where to connect VR_PA ? Thx

Thank you for your answer, I checked the schematics on your link, but they are only using impedance matching network without balun. None of them is using BALFHB-WL-05D3. Could you please give me an example on how to use this balun ?
