The Yebes Observatory has designed and built five VGOS compliant receivers (2-14 GHz bandwidth) for their own radio telescopes and for other European IVS partners under contract or agreement since 2015. Although such receivers are successfully working in their respective sites, we consider that there is still room for some improvements in the receiver design. A second generation of this receiver is going to be built at Yebes Observatory with a new design of the feed and the cryostat. Four of these new receivers are scheduled for 2022. This paper summarizes the firstgeneration receivers built until now and shows the improvements of the second generation.
