Front-End Integration Requirements for the Square Kilometre Array Radio Telescope

Integration technology is discussed for the realization of a square kilometre radio telescope and in particular the Low Noise Amplifier (LNA). Very low noise figures with a room temperature LNA of sub 0.2dB have been achieved with 70nm mHEMT technology.
