So ideally don't you want the S parameters of the ADC front end to match the balun optimially? asked by Steven N.
Yes, s-parameters are a great start but this opens up another subject as well for the match. Since you know the load (R||C combo) what you can do is simply do the math instead. After taking several s-parameters and verfying this ADC measurement technique I have found that over the years that the math gives you just as good of a starting point.

thanks for the response. Is it possible for you to send me the PDF of this article? When I attempt to download it all the figures are lost.
Hi Steven N.,
Attached is the PDF of the article you requested. I also attached a spreadsheet example as well for the AD9467.
