摘要：

New formulas for estimating the spectral regrowth at the output of RF Power Amplifiers (RFPAs) have been proposed. The formulas predict the average output power spectral density (PSD) of fifth-order quasi-memoryless RFPAs, excited with uncorrelated tones. The efficiency of the proposed approach is demonstrated by predicting the spectral regrowth in a commercial RFPA for different input power levels. The obtained results were compared to those of a harmonic balance simulation and have shown a good accuracy and time efficiency.
