A previously proposed look-up-Table based mathematical approach for the modeling of microwave active devices, the Nonlinear Integral Model, is applied for the prediction of intermodulation distortion (IMD) in GaAs MESFETs. Theoretical considerations and experimental results show that the intermodulationcharacteristics of GaAs MESFETs can be predicted with excellent accuracy by using the proposed model together with suitable electron-device-oriented interpolation techniques, directly on the bases of conventional measuremerts (DC characteristics and bias/frequency dependent small-signal S-parameters).

Abstract
A previously proposed look-up-Table based mathematical approach for the modeling of microwave active devices, the Nonlinear Integral Model, is applied for the prediction of intermodulation distortion (IMD) in GaAs MESFETs. Theoretical considerations and experimental results show that the intermodulationcharacteristics of GaAs MESFETs can be predicted with excellent accuracy by using the proposed model together with suitable electron-device-oriented interpolation techniques, directly on the bases of conventional measuremerts (DC characteristics and bias/frequency dependent small-signal S-parameters).File in questo prodotto:
