This chapter givens an introduction to the theory of small signal GaAs MESFETs with particular emphasis on the models used to predict the FET gain and noise figure performance. Such calculations have led to better FET structures and geometries being introduced as a means to exploit the intrinsically superior properties of GaAs over Si. The properties of the dual-gate FET have also been covered in some depth as this particular type of device has proved itself to be especially useful in microwave circuit applications.
