Harmonics of an amplifier [hlp]

[No one]

Hello Everyone;
If we use Gali-3 from minicircuits as amplifier, may any harmonics exist?
You may find the datasheet of Gali-3 at:
https://www.minicircuits.com/pdfs/GALI-3+.pdf

yeah there will be harmoncis , but they may be low , the harmonics will depend on how will u drive ur amp , will it be in sat , where the nonlinear effect is high and so the harmonics will be high

Suppose that amplifier isn't in saturation. What is the level of harmonics respect to desired signal? -40dBc? -50dBc? How much?

it will depend on the amplifier charcteristics , i can't tell from the datasheet , but u can do something nice , in any simulator like ads use the amp model and use the OIP3 and 1 dB compression point and the gain to model the amp , then use the HB simulator , and check the output harmonics , this can give u a crude approximation

Can you upload an example of such analysis in ADS2004?

i don't have one right now , so i need to create it , it will take time , coz i have exams these days
