From MAD to SAD: The Italian experience for SKA-LFAA

The National Institute for Astrophysics (INAF) is deeply involved in the designing phase of the Low Frequency Aperture Array (LFAA) of the Square Kilometer Array (SKA). In particular, the technological contributions of INAF are basically spread in three main areas: (i) antenna and array pattern characterization and calibration, (ii) analog and photonic receiver design, and (iii) development of digital back-ends FPGA-based.
