Microwave performance of 0.25 µm doped channel GaN/AlGaN heterostructure field effect transistor at elevated temperatures
Electronics Letters, 1997•IET
The authors report the DC and microwave performance of a 0.25 µm gate doped channel
Al0. 14Ga0. 86N/GaN HFETs exhibiting a cutoff frequency of 37.5 GHz and a maximum
frequency of oscillations of 80.4 GHz. The calculations of the Fermi level position and
comparison with the expected conduction band discontinuity confirm that the channel in
these transistors is doped. DC and microwave characteristics of these devices do not
change much with temperature up to at least 200 and 90° C, respectively.
