## Dual band S/X crioelectronic block of radio telescope

Transactions of IAA RAS, issue 24, 140–143 (2012)

Keywords: feed systems of radio telescopes, cryoelectronic focal unit, noise parameters, noise temperature

### Abstract

In accordance with the recommendations of the IVS Committee VLBI2010, radio telescopes of the new generation VLBI networks are to receive simultaneous signals in several frequency windows within the frequency band of 2-14 GHz. Feed systems of the radio telescopes, meeting these recommendations, typically require cooling to temperatures of hydrogen level [1]. In the article a cryoelectronic unit that provides cooling the dual band feed and a few low-noise amplifiers is presented.
