TL;DR: A single-input single-output photonic wireless link at 237.5 GHz with record 100 Gbit/s data transmission over 20 m with state-of-the-art active I/Q-MMIC at the receiver is demonstrated.
Proceedings ArticleDOI
Transmission of an 8-PSK modulated 30 Gbit/s signal using an MMIC-based 240 GHz wireless link
J. Antes,S. Koenig,D. Lopez-Diaz,F. Boes,A. Tessmann,R. Henneberger,Oliver Ambacher,Thomas Zwick,Ingmar Kallfass +8 more
TL;DR: The transmission of complex modulated data signals with data rates up to 30 Gbit/s is successfully realized using a 240 GHz wireless link based on active MMIC components as well as a characterization of the RF frontend based on S-parameter measurements and back-to-back signal transmission.
