Hello

please, which is the expression used in ADS for the calculation of the input impedance from the S11 parameter?

I'm not refering to the way to obtain it making use of the function zin(Sii,Zo), but I'm asking how does the program calculate Zin in terms of S11, for example.

Thank you very much
