Senior Scientist

RFIC Design for PLL/Frequency Synthesizers
Science Park 1, Altenberger Straße 69, 4040 Linz, Austria

Silicon Austria Labs is performing cutting-edge research in its world-class mmWave RF Lab on the physical layer of RF systems for future 5G/6G (UE, front and back-haul), and millimeter-wave imaging/sensing/radar applications. In this domain, the mmWave RF Lab collaborates closely with the Johannes Kepler University Linz and leading industry partners on e.g. RF/millimeter-wave transceiver architectures robust in terms of interference and coexistence, reconfigurable RF systems for transceivers and RF/millimeter-wave front-end modules (architectural reuse and/or resource sharing), and large-scale phased-array antennas and beamforming structures, which are targeting millimeter-wave and sub-Terahertz communications (5G, 6G), radars and imagers. In support of the design activities the mmWave RF Lab is equipped with the best in-class test infrastructure covering the GHz and low THz frequency range.
