Abstract


Results of synthesis, design and tests of the experimental sample of cryogenic receiving focal unit (CRFU) for telescopes of Russian radio interferometric complex of new generation are presented. The radio telescopes can receive signals of space radio sources simultaneously in the S, X, and Ka bands. They are partially compatible with radio telescopes of promising global geodesic network VLBI2010. Approved technical solutions of CRFU key units are considered. The main characteristics of microwave elements are shown to satisfactorily correspond to design specification.

Key words: multirange dish antenna feed elements, circular-polarization separators, cooled low-noise amplifiers, radiometers, VLBI2010
