A 650 – 1670 MHz phased array feed package for SKA1 survey

The Square Kilometre Array radio telescope (SKA) will be 100 to 1000 times more sensitive than any radio telescope currently available enabling it to probe key questions in cosmology and physics, including the early origins of the universe. The SKA will be built in two stages “SKA1” and “SKA2”. SKA1 was originally envisioned as being the first 10% of the full SKA, with SKA2 completing the project. SKA1 has three distinct components SKA1_low, SKA1_mid and SKA1_survey.
