DUAL FEED 18-26 GHz RECEIVER

The Dual Feed receiver is an exact replica of the Multifeed receiver; it is cryogenic too and has the same nominal features as the Multifeed, though with a reduced number of feed (2) and channels (4). The feeds of this receiver are optimized for the coupling with the Medicina (IRA-INAF) 32 m antenna. In the picture, there is the complete receiver front-end inside the cryostat with (from top to bottom) the 20K shield, the 20K surface, the 70K surface and the 300K base.
