Evaluation of Envelope-Domain Dynamic X-Parameter Model Based on Variable-Carrier-Frequency Analysis
This paper studies the envelope-domain dynamic Xparameter model of RF power-amplifier nonlinear behavior. Based on the analysis of its fundamental assumptions and the main applications for intermodulation predictions, the consideration of model sensibility to variable carrier-frequency is proposed as one criterion to evaluate the reasonableness of the mathematical modeling. The experimental results in this paper show that the dynamic X-parameters are compatible with each other only within a small neighborhood around the desired carrier frequency, which on one hand may to some extent reflect the reasonableness of the theory, and on the other hand serve to investigate the validity and limits of dynamic X-parameters from a new perspective.
