Abstract :
We present the integration, laboratory verification, and field testing of the first full-size Mk II Phased-Array Feed (PAF) built for the Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope. The ASKAP PAFs are a 94 port × 2 polarisation version of a planar connected “chequerboard” array (Hay and O´Sullivan, Radio Science, 43, no. 6, 2008). They operate over 0.7 GHz to 1.8 GHz and enable each 12 m ASKAP dish to observe a 30 deg2 field of view and survey the sky extremely rapidly.
