The Atmosphere Observing System (AOS) is an international Earth science program to develop a space observatory comprising several satellites. These satellites will fly in two orbits—polar and inclined—to reveal the relationships between aerosols (fine particulate matter in the atmosphere), clouds, precipitation and storms, with a view to improving weather and climate models. The embedded microwave radiometer named C²OMODOR includes a range of channels to measure ice water path, precipitation, atmospheric temperature and humidity. These different channels are centered at 89 GHz, 183 GHz and 325 GHz. In order to address future needs and to improve measurements at these frequency ranges, this internship will focus on the critical building blocks for an innovative receiver implementation. In that context, it is proposed to design an integrated receiver architecture in an advanced BiCMOS process operating at 325 GHz. The evaluation of its RF performances, such as NF, linearity and gain, will allow the comparison with existing discrete III-V solutions.

This internship will be done within a CNES / ST Microelectronics / LAAS-CNRS collaboration.
