BIAS Pin Usage
The SKY66111-11 BIAS pin supplies the bias to the internal PA.
By varying the voltage at this pin, PA operating parameters
including gain, supply current, and efficiency can be adjusted.
The BIAS pin can also be used to adjust the SKY66111-11 output
power when the RF source (transceiver or baseband) has a fixed
level.
