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.
the s11 file measured on the eval board with reference plane at the end of the transmission line.
we don't have s-parameter that de-embed the pcb.
use a shunt 68ohm resistor at the input for simulation…
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?
Can somebody please provide an answer to Magadum's question regarding the difference between the two s-parameter files? I am also interested to know.
The 6ghz data is the de-embeded.
The 10Ghz data is measured on the demo board with reference plane adjusted to the IC. we don't have de embed data up to 10ghz.
I simulated the S11 file available from ADI's website and return loss was about 7dB and expected return loss should be 10dB. What reference plane was used to measure S11?
Do you have the de-embedded S11 measured at IC pins (Differential IN+ and IN-) so that I can design the matching network?
