Millimeter-wave 60 GHz transceivers with RF impairments
Sprache des Titels:
Prof. Roman Mar?álek, Brno University of Technology, Brno, Czech Republic -- Millimeter waves will play an important role in the contemporary and future communication systems. While the frequencies ranging from 24 GHz to 52 GHz are already part of the 5G, the 60 GHz band is attractive for providing unlicensed access to spectra. In contrast to the currently most-used microwave frequencies in the sub-6 GHz band, mm-waves offer channel bandwidths in the range of hundreds of MHz or even wider. On the one hand, such bandwidths allow for elevated data rates, but on the other hand, the wide bandwidth accentuates the effects of wireless front-end impairments on transmitted waveforms and makes their compensation more challenging. The aim of this talk is to present the experiments with mm-wave 60 GHz transmissions carried on at Department of Radioelectronics, Brno University of Technology. After brief description of used experimental test-beds, the basic methods of compensation of the most critical RF front-end impairments will be described. The presentation will be concluded with overview of example applications of the test-beds for power amplifier linearization and data transmission.
