I am using ADS2022 for optimization of Power Amplifier. When I try to do optimization, I could not get proper optimization results. I am getting errors that file is attached below. It seems to be fine. I am not understanding why I am getting this error. Guide me some one how to eliminate this error?

You didn't define optimization ranges. Can you upload the project file with process DK as .7ads format ?

As you asked in the previous posting, I have attached project file with process DK. I request you to address this issue.

Not in this way, save your project as archived format and include PDK in it. ADS will create *.7zads file. Zip it and post here.

Dear BigBoss,
As you asked in the previous post to save project as archieve format and include PDK, I have saved as you mentioned and attached it. Please have a look into it and give suggestions to eliminate the error.

You did some mistakes
-You entered 2 limits that contradict each other in "Goal" blocks. While you're defining a limit less than <> dB in 25-32, you also defined another limit Greater Than <> in the same frequency band. They were in a contradiction.
-You entered "freq" variable without units. You should enter them as 25e9 and 32e9.
Because ADS Optimization Engine does not know which unit you're working on.
I have corrected and re-named the project.You can continue to work but there are some other design problems because dB(S(2,1)) is negative, you have to correct this.
