The Sardinia radio telescope (SRT) is the newest radio telescope that came into operation in ITALY. Due to its dimensions (primary mirror diameter of 64 meters) and the accuracy of surface processing, the SRT is an international instrument for high-frequency observations, over 100 GHz. In particular, two new broadband multi-feed (double polarization) receivers are under construction, which will support the one already operating in the K-band. All three of these receivers will be managed by a back- end, installed in the building where there is also the control room, located more than 600 meters away from the SRT. The race that will be banned will allow the acquisition of RFOF modules/links that will allow to connect the receivers mounted on the SRT with the environment where the back- will be installed via fiber optic cables Digital ends.
The Sardinia radio telescope is being strengthened with the creation of several new receivers that will operate at frequencies above 40 GHz, up to the theoretical limit of 100 GHz for which the radio telescope was built. In particular, two Q- (33-50GHz) and W (77-116GHz) and W (77-116GHz) multi-feed receivers are under development, with 19 and 9 feeds respectively. Once completed, they will join a renewed version of the 14-feeds K-band receiver (18-26.5 GHz) already installed on the antenna. All three multi-feed receivers have in common the same output as the first RF conversion that will be carried out on the antenna in the 1-18GHz frequency band. In order to share the same back end, which will be installed inside the main building 600 m from the antenna, an antenna remote control system based on RFof technology capable of carrying All 38 outputs (19 feeds/2 bias) in the 1-18GHz band is necessary.
This contract will allow to acquire the 40 modules/links in RFEF technology needed to connect the radio telescope with the control room located in the buildings.
