What commponent and which PORT should be include in the schem if I want to analysis 1dB compression and IM3?
Could you please give me an example of @ds project?
Thank you very much.
 

HB Simulation

1dB compression and IM3 measurement can be finished by palacing according components in the Simulation-HB catalog and Simulation-XDB.
 

Could you please give me a project of a simple example, I can't read understand its help.
Thank you very much!!!
 

Setup Harmonic balance analysis.
Insert a voltage source in the schematic.
Sweep the source voltage, e.g. vin
Label the output node, e.g. vout

At the data display, plot dbm(vout) vs dbm(vin)

I guess it is in the manual. Hopes it helps.

you can try to use the template (HB) or explore the example proj. file for LNA/PA design.
