description: The given work is devoted to the development of a microwave waveguide filter with
a metal insert for the frequency conversion unit of the RT-13 radio Ultra-wideband
receiving system. Based on the analysis of the current state of microwave filter development, a waveguide filter design with a metal insert was selected, parameters
were calculated, and computer simulation was performed in the ANSYS HFSS interactive software environment. The results obtained made it possible to develop a
microwave filter with a 2 GHz band. The results of an experimental study of both
the microwave filter itself and the entire modernized frequency conversion unit as
part of the RT-13 Ultra-wideband receiving system of the radio telescope are presented, which showed good agreement between the experimental data and the calculation and simulation data.
It has been shown that expanding the frequency band of the receiver channel provides an improvement in the sensitivity of the receiver both in radiometric and in
radio interferometric modes, which is especially important for the receiving system
of the RT-13 radio telescope, used mainly for VLBI observations.
