Study of Microwave Performances of AlInN/GaN and AlGaN/GaN HEMT Devices up to 18GHz

Abstract : An intensive electrical characterization of AlInN/GaN HEMT devices is presented in this paper. The performances of these devices based on new material are compared with AlGaN/GaN HEMT devices, thanks to the measurement results and the extraction of small-signal models. Our study is based on 8x75μm devices processed by 3-5 Lab. Load-pull characterizations at 18 GHz will show the advantages of this technology at high frequencies.
