Abstract :
A new large-signal equivalent circuit model of a pHEMT with and without illumination has been developed. A HEMT oscillator operating at approximately 31 GHz has been designed and tested, based on this model. The optical tuning frequency range of 31 MHz under a halogen lamp and 60 MHz under a GaAs laser illumination has been observed.
