Abstract
The results devoted to the development of a method for creating an RF transistor, in which a T-shaped gate is formed by nanoimprint lithography, are presented. The characteristics of GaAs p-HEMT transistors have been studied. The developed transistor has a gate “foot” length of the order of 250 nm and a maximum transconductance of more than 350 mS/mm. The maximum frequency of current amplification ft is 40 GHz at the drain-source voltage VDS = 1.4 V and the maximum frequency of the power gain fmax is 50 GHz at VDS = 3 V.
