IAA RAS has already made the radio interferometer which consists of two radio telescopes with dish diameter of 13.2 m. Each radio telescope is equipped with a specially designed receiving system. The main feature of this system is the cryogenic receiving unit that includes cooled triband feed and low-noise amplifiers (LNA). Feed design allows to receive signals in three frequency bands S (2.2–2.6 GHz), X (7.0–9.5 GHz) and Ka (28–34 GHz) for both circular polarizations (LCP and RCP) simultaneously.
