RF Characterization and reliability of a power amplifier cell under large signal operation
Context : In an RF front end module, the power amplifier is the device seeing the harshest conditions with regard to reliability (temperature, voltage). The lifetime prediction of such devices needs appropriate testing and modeling as the current reliability models are solely based on DC measurements. An RF-based model is then mandatory to accurately estimate […] >>

Characterization and reliability of RF switches, study of the substrate impact on performance.
Context: Incoming 5G imposes new challenges on RF devices performance such as operating at millimeter-wave frequencies and harsh constraints on linearity to avoid spectral pollution in the adjacent carriers. The best way to efficiently reduce the level of harmonics is to boost the resistivity of the semiconductor beneath the buried oxide. In SOI (Silicon on […] >>
