Abstract :
The microwave performance of a GaAs MESFET, where a buffer layer of a low carrier concentration is inserted between the gate metal and the channel layer, is calculated and compared with that of a conventional MESFET. It is found that the use of such a high-resistivity buffer layer contributes to a great improvement of the microwave performance of the GaAs MESFET, especially in f
