An addition that I should have included in the prior post:
In my estimation, simulation is good to help work out issues with a design.? Actual measuring should be done for an individual radio.? If you rely on measurements only, you can get into a parts variation problem.? Is your measurement sample large enough to verify the outliers in a production run?
The above is from experience in taking processes from R&D to production.? The results are not always as expected.? This is from food industry experience, but I believe the concept applies.
