  • A wideband detector for the 30 Ghz channel of the Planck mission low frequency instrument 

    Paco Sánchez, Pedro Antonio de; Lázaro Guillén, Antoni; Pradell i Cara, Lluís (GORDON BREACH SCI PUBL LTD, 2000-05-31)
    Article
    Open Access
    Design considerations of a 30 GHz detector prototype for the Planck Low Frequency Instrument (LFI) are presented. A simple detector configuration based on a commercial Schottky diode is used, featuring a good linearity and ...
