Hi, I need to simulate IIP3 with ADS? I found there is a macro in ADS, named ip3_in(Vout,0,(1,0),(2,-1),50) and ip3_out(Vout,(1,0),(2,-1),50), can any one tell me why we need both input third order interception and output third order interception? What is the difference?
If there is a buffer following the LNA? Then how to specify the referrence impedence? Is it still 50ohms? Thanks very much...
