Abstract | This paper presents a new approach for non-linear analysis of power amplifiers based on the n-order polynomial modelling. A general expression for the fundamental frequency output is developed in this paper. It allows considering any order of polynomial model and obtaining analytical expression for the fundamental-frequency output without complex computations, using developed formulas. This model significantly simplifies non-linear analysis of power amplifiers and the process of designing linearizers. This paper also presents a simple approach for obtaining polynomial model from a frequency response of power amplifier. The proposed method is verified by experiments. Obtained polynomial model shows simulation results similar to the measurements for real amplifier. Developed n-order output modelling and proposed model extraction method can significantly simplify, optimize and enhance power amplifiers’ non-linear analysis and behavioural modelling. Proposed modelling approach can be also used to design linearizers. |
