A new analaytical algoritem for the determination of the load reflection coefficient to maximization dynamic range in high frequency power amplifiers

Abstract

In recent decades, S-parameters have been used to model the Linear High Frequency Amplifier behavior. Using the S-parameter, the source and load reflection coefficient can be calculated, which is useful for designing the Input and Output matching network in linear amplifier. The S-parameter cannot model the behavior of the nonlinear amplifiers. X-parameter were introduced to modeling nonlinear amplifier behavior. In this paper we introduce a new algorithm and simulated based on the X-parameter analytical computations, whose purpose is to achieve an optimum load reflection coefficient to minimize the output second harmonic power and increase the dynamic range of a nonlinear amplifier. © 2016 IEEE.
