There is some information about single-ended input impedance, shown in the table 1. It seems the data were measured on the demo board. Can you provide deembedded S-parameters of the LTC5582 up to 10 GHz?
here's single ended impedance s1p data up to 10GHz.
S-parameters up to 6 GHz given in the 5582f.pdf file do not correlate with S-parameters up to 10 GHz given in your arhive (see the image below). Why?
