    This paper describes specifics of the development, manufacturing and performance of the 70 GHz receivers of the Planck Low Frequency Instrument (LFI). Presently, the development, manufacturing, and assembly of the 70 GHz Protoflight Models (PFMs) have been completed, and they have entered their final acceptance testing. The first results from the PFM of LFI 70 GHz receivers have demonstrated state-of-the-art performance with a 29 K noise temperature, 12 GHz effective bandwidth, and a 1/f knee frequency of 68 mHz. The Planck Surveyor Mission will be launched 2007.
