At which pins should I apply DC feed for the sub-GHz and 2.4GHz PA of EFR32?


For the 2.4GHz PA, the DC feed should be applied on PAVDD pin.


On the sub-GHz side, the PA DC feed is required through the TX output pins: SUBGRF_OP, SUBGRF_ON.


For more details, refer to the EFR32 radio board reference designs.
