Set_RfFrequency() command
Set_RfFrequency(RfFreq) is used to lock the RF-PLL frequency to the transmit and
receive frequency.
Set_TxParams() command
Set_TxParams(Power, RampTime) is used to set the transmit output power and the PA
ramp-up time.

Note: The RF-PLL frequency formula is the same for RF-PLL high-resolution
mode and RF-PLL low-resolution mode. In RF-PLL low-resolution mode,
the RF-PLL frequency is set to the nearest low-resolution integer value.
