Exceeding any one or a combination of the Absolute Maximum Rating conditions may
cause permanent damage to the device. Extended application of Absolute Maximum
Rating conditions to the device may reduce device reliability. Specified typical perfor-
mance or functional operation of the device under Absolute Maximum Rating condi-
tions is not implied.

Output stable to within 90% of final gain
Fundamental frequency is between 2400MHz
and 2500MHz; RF P_OUT=+18dBm. See note 2.
Notes:
*The EVM specification is obtained with a signal generator that has an EVM floor of less than 0.7%.
**The PA must operate with gated bias voltage input at 1% to 99% duty cycles without any EVM or other parameter degradation.
Note 2: For best harmonic rejection please refer to the harmonic rejection application schematic.
