Measurement based modeling of amplifiers in deep saturation
Wendy Van Moer, Yves Rolain · 2003
A measurement based black-box modeling method for amplifiers in deep saturation is proposed. To model the amplitude and phase behaviour of an amplifier from the linear region to strong saturation, a rational Volterra model is used. The new model is compared with a standard polynomial Volterra model. The calibrated measurements are performed using the nonlinear network measurement system (NNMS).
