Notes:
1. VCC = 3.3V, VPC = 2.9V, T_A = 25°C, PA is constantly biased, 50Ω system.
2. Power Control bias current is included in the total quiescent current.
3. Measured from Device On signal turn on, (Logic Low) to the point where RF P_OUT stabilizes to 0.5dB.
4. P_OUT measured at P_IN corresponding to power detection threshold.
