Информация о статье Текст статьиАннотация
The report focuses on the new equipment developed in IAA RAS for the astrophysics VLBI 4.6–5.5 GHz (6.2 cm, C-band) band receivers in radiointerferometric network “Quasar”. The purposes were to increase the operational receiver reliability, to to expand the operating frequency band from 500 to 900 MHz and improve the technical characteristics. Low noise amplifiers in cryoelectronic frontend units were replaced with modern and more reliable ones. New dual channel frequency conversion units with integrated local oscillators were designed. Spectral characteristics of local oscillators were improved. Dual channel noise generators units with amplified compensating noise density were developed, their design and technical parametres are given. Modernization of the C-band receivers reduced the number of receiver units and increased overall operational reliability. Due to extended 900 MHz band the improvement of all basic receiving channel parameters is expected.
