Transceiver system for digital data transmission at millimeter range

摘要

In commercial and military fields systems of communication on VHF - basis play very important role nowadays. While projecting such systems several antagonisms arise: ensuring transmission of high- speed streams of data, lowering of radiated signals level and small power consumption. In the system of communication on VHF - basis, which was worked out by our specialists, the type of modulation (with the help of highly effective non-linear scheme), which provides minimum of quantity of energy per each bit of transmitted information, is used. The original technical decisions are realized in used antennas, in power couplers, in filters. The experimental model of system of digital information transmission of frequency 62 GHz and speed of transmission information > 200 Mbit/s was made. At designing system for wireless communication there is a line of technical contradictions. On the one hand, the complex kinds of signals providing high-speed flows of data are necessary for transfer of the qualitative videoimage and a sound, and on the other hand, for increase of profitability and reserve of work it is necessary to reduce levels of radiated signals and power consumption.
