First Experiments on Data Transmission Using a Sub-THz Gyrotron

This paper presents the results of the first experiments demonstrating the possibility of wireless data transmission using a subterahertz band gyrotron signal as a carrier. The output power of the subterahertz gyrotron was modulated by a rapid change in the potential of the currentless anode. The resulting amplitude modulated (AM) signal with the medium power of about 50W was received by the ultrafast THz detector. Successful transmission of an analog sound signal and transmission of a digital signal at a rate up to 1.5Mbps over a distance of about 2m was demonstrated. The investigated approach confirms its potential for data transmission using gyrotron in any frequency band without loss of generality.
