All, Need a SPICE model of a PHEMT or a MESFET transistor. The transistor properties are: Substrate: GaAs Type: Depletion mode Gate width: 0.25um Gate length: 10um Threshold voltage: -1V The transistor enters cutoff at VGS < -1V Note: It's important that the transistor's model will work with a negative VDS voltage, where the Drain and Source are changing their rolls. Any info may help.
