Abstract
The Square Kilometre Array (SKA) is the next generation radio telescope. Aperture Arrays (AA) are considered for SKA-2 for frequencies up to 1.4 GHz (SKA-1 uses AAs up to 350 MHz). This document presents design considerations of this Mid-Frequency Aperture Array (MFAA) element and possible system architectures complying with the SKA-2 system requirements, combining high sensitivity with a superb survey speed. The architectural analyses has been submitted to the System Requirements Review of the MFAA element.
