In my work I want to use the ADL5380. On the website I found CN-0374,where it is used ADL5380. I have a few questions on CN-0374. 1) Why on page 1 for ADA4940-2 Zin=500 Ω, if Rg=249 Ω and Rf=499 Ω, then Zin= 750 Ohm, isn't it? 2) On page 3 stated that power gain = -4.643 dB for the ADL5380. Where is the number? What is the difference between conversion gain and power gain?
