Abstract :
This paper describes the system design and realization of a cryogenically cooled Focal Plane Array (FPA) for radio astronomy application. The system will consist of an antenna array, low noise amplifiers (LNA) and an RF beam former which are placed inside a cryostat. The antenna and the primary LNAs are cooled to 20 K, while the beam former will be at 77 K. The system design and the performance of the overall design are addressed.
