Job title
Analytical Synthesis of Matching Networks and Power Combiners for 6G Radar Applications H/F
Subject
This internship focuses on the analytical synthesis of broadband and dual-band matching networks and power combiners for 6G radar applications. The objective is to develop a component library for integration into an automated power amplifier design flow and to conduct a comparative analysis of amplifier architectures targeting fractional bandwidths greater than 150%.
Contract duration (months)
6
Job description
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.
Methods / Means
Analytical, Matlab, ADS, Python
