2.11.1 Transmitter RF Characteristics
The RAK2245 Pi HAT has an excellent transmitter performance. It is highly
recommended to use an optimized configuration for the power level
configuration, which is part of the HAL. This results in a mean RF output power
level and current consumption.
Note：The maximum output power setting should not exceed 11.73dBm.
