To further increase the observation speed, the new generation of radio receivers use a multi-beam focal plane array (FPA) together with wide bandwidth. In this article, we present the front-end and cryogenic design of the 7-beam FPA double linear polarization receiver for the 64-m primary focus of the Sardinia Radio Telescope. At the end of this article, we show the simulated performances of the front-end receiver and the measurements of the down-conversion section.STAMPAenConference paper10.1117/12.22326252-s2.0-85015045106000385793800050https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9914/1/The-7-beam-S-band-cryogenic-receiver-for-the-SRT/10.1117/12.2232625.short?SSO=12016SPIE.9914E..22VFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation
