The scientists at A.F. Ioffe Physical Technical Institute, Russian Academy of Sciences, decided to restore the production of semi-conductor devices for pulse radiotechniques which was interrupted at the beginning of the 1990s. These devices have recently found wide application in different areas of technology: in ultra broadband apparatuses of communication, geopositioning and following, radars where a signal of high power should be generated for short time intervals. The idea of creating the devices belongs to a group of scientists under the supervision of Kardo-Sysoev.
It is possible to transfer information using very short electrical pulses with the duration less than one nanosecond. The pause between the adjacent pulses is also very short and therefore the volume of information can be enormous. However, powerful transmitters are necessary to send these signals for distances more than 10-15 kilometers. The task has been solved at the laboratory of fast processes at A.F. Ioffe Physical Technical Institute, Russian Academy of Sciences, where a new class of diodes and transistors has been developed. Their combination in the scheme gives the necessary transmitter, the source of ultra short signals in ultra broadband range.
Industrial production of these devices does not exist anywhere in the world for a while but the appropriate market with a turnover of several billion dollars should appear very soon. Russian scientists have a great advantage over their partners from other countries because a significant and unique experience has been accumulated in Russia for many years. "Of course, our western colleagues will catch up with us but at the moment our technologies are more advanced and it pays to buy the devices for ultra broadband systems in Russia. - says Kardo-Sysoev - All the air ultra broadband radars of super high resolution in the USA use our devices."
