SKA AA-low front-end developments (At Cambridge University)
This paper briefly summarizes the on-going work at the University of Cambridge to design a suitable front-end for the SKA AA-low array (Phase I of SKA, 70-450 MHz). This is a collaborative effort between different institutions and comprises of the design and development of a low cost ultra-wideband antenna and a low noise amplifier to meet the ambitious SKA specifications. These components have been tested as single elements and will be further validated as part of a 16-element array called AAVS0 (Aperture Array Verification System 0). © 2012 IEEE.
