Issue Date: | 2018 | Volume: | 2018 2nd URSI Atlantic Radio Science Meeting (AT-RASC) | First Page: | 1 | Abstract: | We describe the design and architecture of PHAROS2, a cryogenically cooled 4-8 GHz Phased Array Feed (PAF) demonstrator with 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 Multiplexing) fiberoptic link, and d) an FPGA-based Italian Tile Processing Module (iTPM) digital backend. PHAROS2 will be mounted at the primary focus of the 76-m diameter Lovell radio telescope (Jodrell Bank Observatory, UK) for technical and scientific validation. | Conference Name: | URSI Atlantic Radio Science Conference (AT-RASC) | Conference Place: | Gran Canaria, Spain | Conference Date: | 28 May-1 June, 2018 | URI: | http://hdl.handle.net/20.500.12386/28211 | URL: | http://www.scopus.com/inward/record.url?eid=2-s2.0-85055845937&partnerID=MN8TOARS | ISBN: | 978-90-82598-73-5 978-1-5386-3764-7 |
