You must plot output power vs input power. And this must be done be regarding that PA's gain is 0dB. The later can be accomplished be calculating Pout-Pin at a point of the linear region and subtracting this result from all Pout values.

But sir, i have to take variable input power to draw to PA plot or only one fixed input power. And after that i have to take correlation between input and output to see the lag . If any document which is explaining it please share with me Thank you
