Agenda
Radio-frequency engineering for space
- Tuesday, 5 March 2019
- 13:45-15:45
- lecture hall Boole, EWI building
European Space Agency
The key challenges in the design of radio-frequency instruments for space will be reviewed. Space environmental aspects will be discussed as well as the practical measures that need to be implemented to assure a high level of reliability. Selected examples will be presented, covering a wide spectrum of applications: from new satellite communication trends, such as active reconfigurable antennas to future scientific RF instruments that will be placed on other planets. Special focus will be put on high-power amplification concepts and integration solutions.
Speaker Bio: Václav Valenta was born in Czechoslovakia and received Master and Doctoral degrees in radio engineering and mathematics from the Brno University of Technology in the Czech Republic and Université Paris-Est in France, respectively. In the past, Dr. Valenta has designed and demonstrated active and passive radar systems operating up to a frequency of 140 GHz. His expertise is in the area of multi-functional RFIC design (SiGe BiCMOS and III-V) covering key functions from amplification, frequency generation/conversion, modulation/demodulation, and heterogenous RFIC integration. Dr. Valenta is currently with the European Space Agency, RF Equipment and Technology Section, running and supporting several R&D projects. Dr. Valenta is responsible for the development of the radio-science instrument "LaRa", which is a scientific payload that will be launched to Mars in the frame of the mission ExoMars 2020.
