Abstract
We present an experimental study of MESFET and conventional HEMT behav ior as a function of temperature and limited to the range from 293 K t o 393 K. We review the main phenomena appearing under high temperature conditions, and their effects on FET performances. The most important degradations concern, except the mobility in HEMT, the noise figure t hat can increase drastically between 293 K and 393 K. However, we pres ent structures which seem to be less sensitive to temperature variatio ns.
