This article gives a detailed overview of the radioastronomic receivers for the Institute of Applied Astronomy of the Russian Academy of Science (IAA RAS) RT-13 fast radio telescopes that are intended for expanding the capabilities of the Russian VLBI network Quasar for continuous observations and joint operations with the global VGOS network. For work with different VGOS stations, IAA RAS has developed two types of receivers: a tri-band (S/X/Ka bands, circular polarizations) and a wideband receiver (3–16 GHz, linear polarizations). The article provides a summary of the development process, schematic diagrams, technical data, and design features. The results of RT-13 observations in single-dish mode and VLBI mode for both types of the receivers are presented. The Russian VLBI complex Quasar was improved significantly by construction of three fast RT-13 telescopes with two types of swappable receivers per each station enabling it to join VGOS networks and obtain necessary observation data.
