Development of setup for on-wafer pulse-to-pulse stability characterization of GaN HEMT transistor in KU-band

Romain Pécheux, Guillaume Ducournau, Riad Kabouche, Etienne Okada, Christian Mondolot, F Medjdoub

We report on the development of a test bench to extract pulse-to-pulse (P2P) stability On-Wafer in Ku-band. The P2P stability is crucial for RADAR performances. GaN HEMT transistors are a promising candidate for RADAR application. However, they typically generate trapping effects, which can…

Wireless Communications in Dynamic Interference : modeling, capacity and applications, Communications sans fil dans des interférences dynamiques : modélisation, capacité et applications

Mauro Lopes de Freitas

This thesis focuses on the study of noise and interference exhibiting an impulsive behavior, an attribute that can be found in many contexts such as wireless communications. This interference is characterized by the presence of high amplitudes during short durations. In fact, these undesirable…, Cette thèse se concentre sur l’étude du bruit et des interférences présentant un comportement impulsif, un attribut que l’on peut retrouver dans de nombreux contextes comme les communications sans fil. Cette interférence est caractérisée par la présence d’amplitudes élevées pendant des durées…

Optimisation de guides optiques à absorption linéaire

Vincent Magnin, Joseph Harari

Il est remarquable d’obtenir une absorption optique quasiment constante. Cela est rendu possible par l’utilisation de nano-guides optiques dont la largeur du cœur peut être réduite avec le profil voulu afin de déconfiner progressivement le mode optique.
