Fundamental frequency is between 2400MHz

and 2500MHz; RF POUT=+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.
