W4EF said: >presenter showed several IMD curves for class B amplifiers that had high level "sweet spots" where the positive slope of IMD level as a function of input power actually reversed and formed a local minimum at a fairly high input power level.< Yes, Mike, it's a well documented phenomena, and has been known for many years - at least amongst the professional engineering community, as well as a few hams. 73 Peter G3RZP _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
