The 64 m diameter Sardinia Radio Telescope (SRT) has recently started an early science program using three cryogenic front-ends covering four bands: P-band (305-410 MHz), L-band (1.3-1.8 GHz), high C-band (5.7-7.7 GHz), K-band (18-26.5 GHz).
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
