IIP2 and IIP3 plot in LNA

Hi,
Can anyone help me in calculating IIP2 and IIP3 for LNA using ADS. What are the equations used to calculate those.


Thank you

There is a OIPn measurment block in s-parameters simulation palette,use it with low driving level at least 20dB lower than P1dB.Then extract the Gain of your LNA from this value.
