    An overview will be presented for the Planck Mission to measure Cosmic Microwave Background (CMB) radiation anisotropies with an accuracy better than ever. Special attention will be given to the development, manufacturing and performance of the 70 GHz receivers of the Low Frequency Instrument (LFI). Sensitivity of the receivers is based on state-of-the-art InP MMICs. Presently, the Engineering Model (EM) has been completed and manufacturing of the Proto Flight Model (PFM) is ongoing. The EM of LFI 70 GHz receivers have demonstrated performance with a 43 K noise temperature, 7 GHz effective noise bandwidth, and a 1/f knee frequency of 40 mHz. For the PFM a new MMIC run has been made and the amplifiers achieve a noise temperature of about 25 K, when cooled to 20 K.
