Planck mission with advanced cryogenic mm- and submm-wave receiver arrays

This paper presents an overview of the Planck mission with specifics on the development, manufacturing and performance of the 70 GHz receivers of the low frequency instrument (LFI). Presently, development of the elegant breadboard model (EBB) has been completed and designing and manufacturing of the engineering model (EM) is ongoing. The EBB of LFI 70 GHz receivers has demonstrated state-of-the-art performance with a 30 K noise temperature, 16 GHz bandwidth, and a 1/f knee frequency of 30 mHz. Flight model manufacturing starts in Fall 2003.
