The purpose of this letter is to present an experimental analysis of the temperature effects on the small-signal equivalent circuit of a GaN HEMT. With the aim of contributing to the exploration and advancement of this technology for high-power and high-temperature applications, the major intrinsic RF figures of merit together with the positive derivative of the real parts of the impedance parameters versus frequency are deeply investigated versus ambient temperature.

Abstract
The purpose of this letter is to present an experimental analysis of the temperature effects on the small-signal equivalent circuit of a GaN HEMT. With the aim of contributing to the exploration and advancement of this technology for high-power and high-temperature applications, the major intrinsic RF figures of merit together with the positive derivative of the real parts of the impedance parameters versus frequency are deeply investigated versus ambient temperature.File in questo prodotto:
