view from behind the cold box

The cold box is not shown in this view so that we may see the components within. In the centre of the image lie the four cooled Low Noise Amplifiers which are made at Chalmers University of Technology. These are for the subMM IF amplification. Below this, in red, is the ring filter where LO for the 119GHz receiver is directly coupled by waveguide. Next to this is another LNA made by Chalmers for the 119GHz IF. The 119GHz receiver is built by Ylinen Co. of Helsinki, Finland.
