UDC 621-37 DOI: 10.14529/ctcr150308 Application of Russian Element Base in Broadband Digital Devices for Processing and Generating of Radio Signals Yu. T.

Povalyaev, South Ural State University, Chelyabinsk, Russian Federation, svp.drts@gmail.com Abstract The article describes the principles of modern broadband devices for processing and generating radio signals. It found that the high-speed programmable logic integrated circuits (FPGA), analog-todigital (ADC) and digital-to-analog (DAC) converters are the key components of broadband radioelectronic systems. Specifications of the Russian FPGA, ADC and DAC are given. It is shown that the Russian high-speed FPGA, ADC and DAC are inferior to their foreign analogs in many ways. This hampers their direct use in digital broadband devices for processing and generating radio signals. For example the maximum clock frequency of high-speed Russian ADC doesn't exceed 125 MHz. At the same time the maximum clock frequency of foreign ADC is up to 1000…5000 MHz. Specialized blocks for digital signal processing (e.g. serial digital data transmission channels with a bandwidth of several gigabits per second) miss from the Russian FPGA. Foreign FPGA have tens of such specialized blocks. Problems of measuring the frequency of radio signals over a wide frequency range and rate matching digital streams between Russian FPGA and DAC are analyzed. It is shown that the application of special technical solutions and algorithms allows to build the broadband digital device for processing and generating radio signals on the Russian element base. For example the use of monobit digital technology allows to evaluate the frequency of the signal over a wide frequency range at the minimum requirements to the applied digital chips.
