Abstract :
In this paper, large signal IMD sweet spots in microwave power amplifiers are investigated and predicted using a new mathematical basis. This type of nonlinear model enabled the design of power amplifiers specially tailored to present a desired IMD versus drive level pattern. Finally, illustrative application examples are presented.
