Fit the S21 curve to 4th order polynomial. AssignAve gain = |S21| measured between 1.5 and 2.5
GHz. Determine 3dB point from polynomial fit to S21 curve.
Ripple cacluation is defined the difference between measured S21 value (dB) and a 4th order (or less)
polynomial fit for S21 (dB) for frequency range = 0.1 to 12 GHz.
