Terahertz ultra wideband communication system development
For the first time in Ukraine a prototype of the "point-to-point" wireless communication system in terahertz frequency band of 130-132 GHz was developed with usage of impulse ultra wideband signals for local computer networks and sensors data transmission networks which based on the proposed “non-energy” reception method of impulse ultra wideband signals.
The method of "direct" generation of impulse ultra wideband signal for the terahertz band is theoretically proposed and experimentally tested. The experimental layout was designed for the study of impulse ultra wideband signal of nanosecond duration transmission and reception by the method of heterodyne conversion through the wireless channel of the terahertz frequency band of 130-132 GHz.
The simulation model and the structural scheme of the impulse ultra wideband signals transmitter for the transmission path and the receiver based on the method of "non-energy" reception for the reception path of the terahertz frequency band wireless channel are developed.
The experimental layouts of the elements and nodes of the tranmission and reception paths of the terahertz frequency band using photonics and microwave electronics technologies were designed. New circuit-technological solutions for heterodyne development in the terahertz frequency band on the basis of quasi-optical and spatial power summation methods, higher-frequency frequency converters with pumping on the main harmonic and devices with increased frequency selectivity were proposed.
The recommendations for development telecommunication system with optimized sensitivity characteristics and reliability of the information reception for the local computer networks and sensor networks, development of the wireless space communication and radio communication networks between aerostartospheric telecommunication platforms based on the technology of impulse ultra- broadband signals in the terahertz frequency band usage the are proposed.
