Linear and Non linear HEMT model

[Hoque_bd]

Hi,
What are the differences between linear and non linear HEMT model? What is the relation of biasing to linear and non linear HEMT model?

The difference is exactly the same as linear small-signal vs. nonlinear large-signal with any other transistor technology (BJT, MOSFET, JFET, etc.). Understand that and you have your answer.
