Spectral regrowthSimple and accurate nonlinear behavioral models of power amplifiers (PAs) are required whena total radio-frequency (RF) transceiver is designed, especially on a board, because the simula-tion time depends on the complexity of the model. The wideband code division multiple access(W...

power seriesNew 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...
