  • Abstract
    A modified quasi enhancement-mode pHEMTs RF large-signal model is presented which achieves a good agreement with the device performance. This model is based on the Curtice model, by modifying the formula to have a detailed description about non-linear microwave behaviors. The output digital spectra of quasi enhancement-mode pHEMTs can be well predicted by this model, including the ACPR and non-linear spectra regrowth characteristics.
