Présentation de la société : CEA
Le CEA est un acteur majeur de la recherche, au service des citoyens, de l'économie et de l'Etat.Il apporte des solutions concrètes à leurs besoins dans quatre domaines principaux : transition énergétique, transition numérique, technologies pour la médecine du futur, défense et sécurité sur un socle de recherche fondamentale. Le CEA s'engage depuis plus de 75 ans au service de la souveraineté scientifique, technologique et industrielle de la France et de l'Europe pour un présent et un avenir mieux maîtrisés et plus sûrs.
Implanté au cœur des territoires équipés de très grandes infrastructures de recherche, le CEA dispose d'un large éventail de partenaires académiques et industriels en France, en Europe et à l'international.
Les 20 000 collaboratrices et collaborateurs du CEA partagent trois valeurs fondamentales :
• La conscience des responsabilités
• La coopération
• La curiosité
Missions
The aim of this internship is to develop wideband or dual-band matching networks and power combiners using an analytical approach that enables the direct synthesis of these components from specified performance requirements. The candidate will be responsible for implementing a library of analytically synthesized components, which will be integrated into the automated design flow for wideband power amplifier architectures currently under development within the team.
A comparative analysis of two power amplifier architectures will be conducted to evaluate their potential to achieve fractional bandwidths exceeding 150%, thereby covering the 2–40 GHz frequency range. This internship may lead to a Ph.D. focused on the design of an ultra-wideband power amplifier capable of delivering more than 10 W over the 2–40 GHz band, with energy efficiency exceeding 15%, based on GaN technology.
