Hello There
I have some problems and concerns running Load Pull simulation in ADS:
[1] I run the Load Pull simulation (after doing it several times in order to get the optimum area to scan) and I get satisfying results, but still I have some problems. One of them is that the run seems too sensitive to the changing of the parameters, for example if I increase the radius of the circular area just a little bit the embedded harmonic balance simulator inside the Load Pull simulation template gives convergence error problems and finally the Load Pull contours get casual. Is it natural? Should I add stabilizing circuit(s) before running the test? while device is unconditionally stable.
[2] Second problem of mine is that I'm running the Load Pull test for a device and in it's datasheet the Load Pull counters and results for five frequency is given, I'm trying to run the Load Pull in order to get the exact results stated in the datasheet but my simulation gives me different results and even much better ones! while i run the test in the exact conditions stated in the datasheet and I also have valid model of the device provided by the manufacture.
Thank you so much in adance
