Conception et réalisation d'amplificateur de puissance MMIC large-bande haut rendement en technologie GaN

Abstract : This work focus on the design of wideband and high efficiency GaN MMIC high power amplifiers for military applications such as radar and electronic warfare. The main objectives consist in finding innovative power combining structures in order to decrease the overall size of amplifiers and increasing their efficiency at the same time. For these matters, an important part of this work consisted in the design and realization of ultra compact and low loss power combiners. Once the combiners realized and measured, they are integrated into power amplifiers to prove their functionality and the advantages they bring. Several kind of amplifiers have been realized whether regrind their architecture or their performances.
