Type: preprint
Abstract: The Yebes Observatory of the Spanish Instituto Geográfico Nacional (IGN) has developed a simultaneous tri-band (S/X/Ka) low-noise cryogenic receiver for geodetic VLBI observations with VGOS-type radio telescopes, as the ring-focus antennas of the RAEGE network project. This receiver operates in the S (2.2 - 2.7 GHz), X (7.5 - 9 GHz) and Ka (28 - 33 GHz) bands, simultaneously, in order to be backward compatible with legacy VLBI stations and forward compatible with X/Ka VLBI ones.
