I have simulated HSMS 2855 agilent diode in ADS but the plot of output voltage vs the input RF power level simulated in ADS is not like that of the datasheet. Attached is the document containing the schematic, the simulation plot and the desired plot.
Please help me out.
In general, there could exist many reasons that ADS simulation results could diverge from a manufacturer's datasheet:
* Source of the vendor data: are the plots from measured data or simulated data? If measured data, what was the measurement technique? How much uncertainty due to possible measurement error? If simulated data, what simulator was used? If it was ADS, is the setup identical to your setup?
* Uncertainty in the model; nonlinear modeling by its very nature is not an exact science
