The L- and the P-bands can be observed simultaneously with a single coaxial receiver installed at the primary focus, while a seven beam K-band receiver and a mono-feed high C-band receiver are installed, respectively at the secondary and beam waveguide focus. Additional front-ends are under construction to further expand the telescope observing capabilities. We report on the design and performance of the front-ends already installed on SRT and give an overview of the new ones to be completed in the near future.ELETTRONICOenConference paperhttps://www.nrao.edu/meetings/isstt/2016.shtmlhttps://www.nrao.edu/meetings/isstt/papers/2016/2016000043.pdfFIS/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
