| Abstract(in English) | A model is investigated to explain the difference of IM distortion performances of microwave FET amplifiers depending on bias circuit impedance for separation frequency (Δ) of 2-tone signals. The model is moving bias point model with frequency of Δ. It predicts that better IM3 performance will be obtained with low impedance bias circuit at AB-class high drain voltage bias condition, though, better IM3 performance will be obtained with high impedance bias circuit at A-class low drain voltage bias condition. Measured results agree with the prediction. To verify of the model, measured IM3 and calculated IM3 are compared. The calculated values are obtained based on measured AM-AM, AM-PM characteristics of the FET amplifiers, which are biased with consideration of the moving bias point model. A good agreement of these values supports the model. |
