Abstract
A front-end system for receiving signals such as RF signals in a mobile radio communication network includes a cooled vessel such as a cryostat. The cooled vessel includes a manifold that is coupled to the antenna, which separates the various signals received from the antenna. The system includes filters for each signal where such filters are located inside the cooled vessel and may be superconducting. The system may include amplifiers, each of which filters a separate signal from the manifold or may include an amplifier which amplifies the signals before they reach the manifold. The system may also include a wide-band filter which filters the signals prior to amplification or coupling to the manifold.
