Thermal characterization using optical methods of AlGaN/GaN HEMTs on SiC substrate in RF operating conditions

Leny Baczkowski, Jean-Claude Jacquet, Olivier Jardel, Christophe Gaquière, myriam moreau, Dominique Carisetti, Laurent Brunel, Franck Vouzelaud, Yves Mancuso

Performance and reliability of wide bandgap high-power amplifiers are correlated with their thermal behavior. Thermal model development and suitable temperature measurement systems are necessary to quantify the channel temperature of devices in real operating conditions. As a direct temperature...

High density terahertz frequency comb produced by coherent synchrotron radiation

S Tammaro, Olivier Pirali, P Roy, Jean-Francois Lampin, Guillaume Ducournau, Arnaud Cuisset, Francis Hindle, Gaël Mouret

Frequency combs have enabled significant progress in frequency metrology and high-resolution spectroscopy extending the achievable resolution while increasing the signal-to-noise ratio. In its coherent mode, synchrotron radiation is accepted to provide an intense terahertz continuum covering a wide...

Experimental analysis of Zigbee RF signal performance for railway application: Study on a laboratory reduced scale train

Sara Iben Jellal, O. Cohin, S. Baranowski, Ulrich Biaou, Michael Bocquet, Atika Rivenq

Due to its cost and power performance, Zigbee is widely used and can be applied to railway systems. This paper deals with the performance of a Zigbee (IEEE.802.15.4) RF signal, according to several criteria; this analysis is based on an experimental approach and specially on power measurements in...
