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
