Abstract: The nonlinear phenomenon of power amplifiers and its affections on the performances of communication system are discussed.Nonlinear distortions in MESFET amplifiers are analyzed with a general Volterra series.The effects of the nonlinear parameters,the source impedance and the load impedance on intermodulation distortion are researched.Therefore,some important references are provided for the linearization of PAs.

Key words: power amplifier(PA), nonlinear distortion, volterra series
