Abstract. The paper describes  methods of constructing a multi-channel millimeter wave  radio astronomy receiver with spectral separation of channels on the radio frequency. The results of the development of an 8-channel receiver at 30-40 GHz with a channel bandwidth of 900 MHz  in microstrip performance and at 38-46 GHz with a channel bandwidth of 250 MHz in the waveguide performance are presented. The characteristics and results of the developed schemes and units of multi-channel receiver are given.

Key words: radio astronomy, radio telescope, multichannel receiver, spectral separation of channels, microstrip and waveguide performance, power dividers,  pass band filters.
