Broadband Receiver Developments for VGOS Radiotelescopes at Yebes Observatory
Year: 2025
Type: article
Abstract: The Yebes Observatory, a department of the Spanish National Geographic Institute (IGN-Spain), has a distinguished history spanning over 35 years in the development of advanced radio astronomy receivers, including those tailored for Very Long Baseline Interferometry (VLBI). Since 2015, Yebes is a Technological Development Center within the International VLBI Service for Geodesy and Astrometry (IVS). This presentation highlights recent advancements in receiver technology achieved at the Yebes Observatory, emphasizing the design and construction of three cutting-edge broad-band receivers for the VLBI Global Observing System (VGOS) operating across the2-14 GHz frequency range. Among these receivers, one has been specifically developed for the Matera VGOS station in Italy, equipping it to join the VGOS core network shortly. The presentation will cover the key stages of design, development, integration, and testing, following the whole signal chain from the front-end to the backend.
