Role in the project

DICE major contribution to DOT7 will be the design and characterization of technology benchmark circuit blocks and application near circuit blocks which are commonly used for radar sensors (LNAs, PAs, Mixers,…). The operational frequency range targeted at will be between 76 and 240 GHz. Additional contributions will be in the characterization and modeling of passive devices and in realizing a radar application demonstrator.

Erich Kolmhofer was born in Linz, Austria, in 1971. He received the Dipl.-Ing. and Dr. techn. degrees in Mechatronics from the Johannes Kepler University, Linz, Austria in 1998 and 2003, respectively. He joined DICE in 2004 and was involved in establishing DICE’s automotive radar development team in various positions. Currently he is development head for automotive radar products at DICE. Dr. Kolmhofer is author or co-author of numerous publications in the field of microwave semiconductors and microwave engineering.

Herbert Jäger was born in Linz, Austria, in 1975. He received the Dipl.-Ing. degree in Electrical Engineering from the technical University TU Wien with honors in 2000. From 2001 to 2003, he worked with M/A-COM in Cork, Ireland as design engineer on mobile phone power amplifiers. At the same time, he worked towards a Ph.D. degree with the University of Linz. After finishing his doctoral thesis titled he joined DICE in 2003 as head of the component verification group. Since 2004, he is with the Radar Concept Engineering group of DICE. Dr. Jäger is author or co-author of numerous publications on microwave devices and related topics.

Günter Haider was born in Mauthausen, Austria, in 1965. He received the Dipl.-Ing. degree in mechatronics from the Johannes Kepler University, Linz, Austria, in 1997. Prior to his studies, he worked for Engel Maschinenbau Ges.m.b.H., Austria (1984 – 1990).
In 1997, he joined the Fraunhofer Institut für Integrierte Schaltungen in Erlangen, Germany. In 1998, he joined the Danube Integrated Circuit Engineering (DICE) in Linz, Austria. He is leading the Circuit Design Team for 77-GHz integrated radar transceivers. His research interests include circuit design for millimeter-wave and microwave radar sensors.

Christoph Wagner was born in Zwettl, Austria, in 1980. He received the Dipl.-Ing. (M.Sc.) and Dr. techn. (Ph.D.) degrees in Mechatronics from the Johannes Kepler University, Linz, Austria in 2006 and 2010, respectively. After one year at DICE he became a member of the Christian Doppler Laboratory for Integrated Radar Sensors in 2007. Since 2010 he is with DICE again where he is currently responsible for the development of 77-GHz integrated radar transceivers. Dr. Wagner has authored or co-authored more than 30 journal and conference papers and is the recipient of e number of prizes, among them the 2010 IEEE Microwave Prize.
