On the Stationarity Time of a Vehicle-to-Infrastructure Massive Radio Channel in a Line-of-Sight Suburban Environment

Nor El Islam Dahmouni, Pierre Laly, Marwan Yusuf, Gauthier Delbarre, Martine Liénard, Eric Simon, Davy Gaillot

Massive multiple-input multiple-output (mMIMO) communication systems are a pillar technology for 5G. However, the wireless radio channel models relying on the assumption of wide-sense stationary uncorrelated scattering (WSSUS) may not always be valid for dynamic scenarios. Nonetheless, an analysis…

Self-heating temperature measurement in AlInN/GaN HEMTs by using CeO2 and TiO2 micro-raman thermometers

R. Strenaer, Y. Guhel, G. Brocero, C. Gaquiere, B. Boudart

Thermal characterization of GaN-based components is an important and challenging issue that requires the measurement of the self-heating temperature of the channel, the metal contact surface and the substrate with high accuracy. This paper points out that all these thermal parameters can be…

Impact of undoped channel thickness and carbon concentration on AlN/GaN-on-SiC HEMT performances

Kathia Harrouche, Srisaran Venkatachalam, François Grandpierron, Etienne Okada, Farid Medjdoub

We report on a vertically scaled AlN/GaN HEMT technology design optimization for millimeter-wave applications. The undoped GaN channel thickness and carbon concentration into the buffer are extensively varied and systematically characterized. It is found that a thin GaN channel, typically below 150…
