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.
