Statz Model-Statz (Raytheon) GaAsFET Model

Statz_Model:Statz (Raytheon) GaAsFET Model

The PSpice Level 2 GASFET and HSpice Level 3, SAT2 JFET or MESFET models are translated to the ADS Statz_Model. For translation information on the GaAsFET device, refer to Zxxxxxxx. For translation information on the JFET device, refer to JFET Device.

For more information on the ADS model, place the model in a schematic and choose Edit > Component > Edit Component Parameters to view the model parameters. You can also click Help in the component editor dialog box for additional information.

Example SPICE Command Line:

Spice2/3: .model Zmodel NMF VTO=2.- BETA=-1.0e-3...
PSpice: .model GNOM GASFET LEVEL=2 [param=value]...
