PA Characteristics
Shown below is the gain vs Pout over frequency of SKY66397-12 PA for a single carrier CW tone at 2.49GHz, 2.59GHz, 2.63GHz,
and 2.69GHz respectively in band n41 operation(2.5-2.7GHz). It can be observed that the carrier at 2.69GHz experiences a gain of
less than 1dB compared to the carrier at 2.49GHz at lower powers, and a gain of less than 2dB at higher power levels.

The forward gain(S21) of the PA vs frequency is shown in Figure 75. The operating range of this PA is 2.5-2.7GHz. It can be
observed that the gain is not constant across the operating frequency of the power amplifier.
