Arbitrary loadpull behavioral model

Hi,
I am looking for a way to implement a behavioral model of a power source or power amplifier which is able to generate a given arbitrary loadpull contours.
I don't have any loadpull data or real measurement I can import. What I have is just a set of output power numbers in excel in the gamma_x and gamma_y space.
I want to be able to perform an Harmonic Balance simulation with an RF source that is behaving exactly as those output power vs. load Gamma.

Thanks!

There is a way to do this, as described in the attached document. You would enter the load pull data into an MDIF file. I expect you will have to experiment a little to get this to work.

I am curious why you want to do this type of simulation. If it is proprietary you could reply to me at andy_howard@keysight.com.
Thanks.
