. La-maturation-de-la-technologie-gan-en-vue-de-l, avènement d'une filière intégrée prometteuse permettant la réalisation de mélangeurs, d'oscillateurs contrôlés en tension (VCO) ou encore d'amplificateurs faible bruit (LNA) représente un enjeu technologique majeur. Les travaux réalisés ici s'inscrivent dans la complémentarité de tout ce qui a été fait jusqu'à présent en
