Este artigo propõe um novo método de análise de distorção para amplificadores FET dependentes de frequência, que utiliza um novo modelo de série de potências complexas dependentes de frequência (FDCPS). Este modelo consiste em um amplificador não linear independente de frequência representado por uma série de potências complexas de ordem ímpar e filtros de entrada e saída dependentes de frequência. As características de frequência dentro da banda da região de saturação são representadas pelo filtro de saída dependente da frequência, enquanto as características de frequência dentro da banda da região linear são representadas pelos filtros de entrada e saída dependentes da frequência. Neste método, a análise no domínio do tempo é realizada para calcular as características do amplificador não linear independente da frequência, e a análise no domínio da frequência é aplicada para calcular as características do filtro de entrada e saída dependentes da frequência. A intermodulação de terceira ordem (IM3) calculada por este método para um amplificador GaAs MESFET está de acordo com os resultados numéricos obtidos pelo método Harmonic Balance (HB). Além disso, o IM3 calculado por este método também concorda bem com os dados medidos para um amplificador GaAs MESFET de 3 estágios e banda L. É mostrado que este método é eficaz para calcular a distorção dependente da frequência de um amplificador não linear com sinais de modulação de banda larga.

Abstract: This paper proposes a new distortion analysis method for frequency-dependent FET amplifiers, which uses a novel Frequency-Dependent Complex Power Series (FDCPS) model. This model consists of a frequency-independent nonlinear amplifier represented by an odd-order complex power series and frequency-dependent input and output filters. The in-band frequency characteristics of the saturation region are represented by the frequency-dependent output filter, while the in-band frequency characteristics of the linear region are represented by the frequency-dependent input and output filters. In this method, the time-domain analysis is carried out to calculate the frequency-independent nonlinear amplifier characteristics, and the frequency-domain analysis is applied to calculate the frequency-dependent input and output filter characteristics. The third-order intermodulation (IM3) calculated by this method for a GaAs MESFET amplifier is in good agreement with the numerical results obtained by the Harmonic Balance (HB) method. Moreover, the IM3 calculated by this method also agrees well with the measured data for an L-band 3-stage GaAs MESFET amplifier. It is shown that this method is effective for calculating frequency-dependent distortion of a nonlinear amplifier with broadband modulation signals.
