A New Software Package for the Analysis and Optimization of Linearized Microwave Power Amplifiers

This paper describes a new software package developed to analyze and design linearizer systems. Linear and nonlinear devices are characterized by means of their transfer function and descriptive function respectively, while the match is supposed to be ideal in all the access ports. It is based on the first harmonic assumption so that the multitone response is obtained from the single tone one. The algorithm that has been employed is fully numerical and does not require previous curve fitting. The transformation is then performed in a very fast and accurate way allowing optimization with moderate CPU time expense.
