Hello , I noticed that my QPA2575 datasheet doesnt have any smithchart matching data.
which is intresting because other components like the component attached.
I hve only S-param model of QPA2575.
can i do load pull? or matching smith chard circles as shown bellow with only S-param model?
What benefit can i extract from the S-param model to descover the properties of the amplifier.
I know there are NF circles ,Gain circles etcc.. but i am not sure what can be done with S-param model?
Thanks.
