The Millimetron Space Observatory will be equipped with the cryogenically cooled instrument for a Space-Earth Very Large Baseline Interferometry (S-E VLBI). It will be a multi-channel heterodyne receiver with 7mm, 3mm, 1.3mm and 0.8mm channels. The VLBI instrument will have a multi-frequency capability, provided by signal splitting in the input optics and by back-end functionalities. The optical design is shown in this report.

Millimetron Space Observatory will be equipped with the cryogenically cooled instruments for a Space-Earth Very Large Baseline Interferometry (S-E VLBI). It will be a heterodyne multichannel receiver including 7mm, 3mm, 1.3mm and (presumably) 0.8mm channel. Two low frequency channels will be based on HEMT amplifiers, while for the high frequencies superconductor-insulator-superconductor (SIS) receivers will be utilized. The VLBI instrument will have a multi frequency capability allowing simultaneous observation using several channels. This mode has a high potential for improving of black hole event horizon observations due to phase transferring capabilities. The multi frequency observation will be provided by a signal split in the input optics and by back-end capabilities.
