Issue Date: | 2018 | Volume: | XXII RINEM Riunione Nazionale di ElettroMagnetismo | Abstract: | We describe the design and architecture of PHAROS2, a cryogenically cooled 4-8 GHz Phased Array Feed (PAF) demonstrator with a digital beamformer for radio astronomy application. The instrument will be capable of synthesizing four independent single-polarization beams by combining 24 active elements of an array of Vivaldi antennas. PHAROS2, the upgrade of PHAROS (PHased Arrays for Reflector Observing Systems), features: a) commercial cryogenic LNAs with state-of-the-art performance, b) a “Warm Section” for signal filtering, conditioning and single downconversion to select a ≈275 MHz Intermediate Frequency (IF) bandwidth within the 4-8 GHz Radio Frequency (RF) band, c) an IF signal transportation by analog WDM (Wavelength Division Mutiplexing) fiber-optic link, and d) a FPGA-based Italian Tile Processing Module (iTPM) digital backend. | Conference Name: | XXII RINEM Riunione Nazionale di ElettroMagnetismo | Conference Place: | Cagliari, Italy | Conference Date: | 3-6 September, 2018 | URI: | http://hdl.handle.net/20.500.12386/28254 | URL: | http://www.elettromagnetismo.it/wp-content/uploads/2018/09/XXII-RiNEm-Conference-Proceedings.pdf https://sites.unica.it/rinem2018/ |
