Abstract :
A new large signal model of GaAs MESFET is proposed. A commercial packaged high power MESFET (Fujitsu FLC103WG) is adopted for the extraction. Both the hot and cold condition measurements and the pulsed I/V measurement are performed to derive the model. A simple single-stage class-AB amplifier is subsequently built so as to verify the derived model. The simulation and measurement results of the intermodulation distortion of this amplifier are compared
