Bergische Universitaet Wuppertal

The High-Frequency and Communication Technology Department is located at the University of Wuppertal in Germany. Our research involves electronic circuits and systems for future mmWave and terahertz technologies. The research activities span across Terahertz Science for applications such as imaging, spectroscopy, chemical/biologic identification, hidden object detection, and communication with ultra-high data-rates.

Role in the project

In Dotseven, the University of Wuppertal will be involved in the technology benchmarking through the design of circuit building blocks and the evaluation of the technology for new applications as part of the work package four (WP4). Circuits that target applications at very high frequencies can potentially be used in next-generation Communication Demonstrator towards 100Gbps, 3D THz Imaging Demonstrators and Mixers.
