Abstract
We present the design and realization of 3 GHz cryogenic low noise amplifie rs used as IF amplifiers in a radio-camera receiver (SISYFOS project) which is to be installed in the Onsala 20 m millimetre wave telescope. We show t hat a very simple and compact input design provides good matching over a br oad bandwidth while ensuring the stability of the amplifier. The minimum no ise temperature and the gain of the amplifier measured at cryogenic ambient temperature over the specified bandwidth are 7 K and 28 dB respectively.
