  • Abstract
    We present early results of noise temperature measurements made on a Planck LFI EBB Ka-band low noise amplifier at physical temperatures as low as 1.5 K. This temperature is an order of magnitude lower than typically used on radio astronomy receiver systems. The results are tentatively compared with semi-empirical predictions made by Pospieszalski.
