Hi Tony,?
Thanks for the feedback.?
I am afraid you missed my point. First, I never said I would use s parameters to emulate a non linear aspect of the model. However, the point of the validation exercise is to satisfy the criteria that the s parameters of the non linear model... Spice model... operating in a linear manner meet the s parameters of the measured device. Many of them do... spot on. And other models fail miserably.?
Second point, the use of s parameters actually can produce a very excellent STARTING point for successful non linear design. I have applied such techniques to both power amplifiers and one and two port oscillators.?
Again, I emphasize they provide an excellent initialized starting condition. That is to say, ?find embedding networks, matching elements and resonator development in oscillator applications.?
