AD9375-W Return Loss Reg.

You can download the S parameter files from the below link:

Hi,

I am trying to design my front end with the S-parameter from below link,

https://form.analog.com/Form_Pages/Catalina/CatalinaDesign.aspx?prodid=AD9375

My assumption is, The s-parameter data contains the Impedance data of AD9375 measured at BGA balls,they do not exhibit the Return loss characteristic done by the matching circuit of AD9375-W evaluation board. is it right?

I need the return loss data with the wide band matching done as per AD9375-W SCH.

also, In AD9375-W SCH, You have used 43nH LQW18AN43NJ00D for TX output biasing which has a SRF of 2.7GHz. Is it ok to use Inductor with less SRF than output frequency(6GHz)?

Thanks,

Deva

Yes, correct. 

You can consider a return loss of better than 10dB for all frequencies on our Wideband EVB.
