The receiver module consists of passive and active sections that can be incorporated in a very compact mechanical assembly suitable for integration in a focal plane array. The passive section of the receiver module employs a broadband backward-coupler waveguide OMT while the active section consists of ultra-low noise MMIC (Monolithic Microwave Integrated Circuit) amplifiers.ELETTRONICOenConference paperhttp://www.elettromagnetismo.it/wp-content/uploads/2018/09/XXII-RiNEm-Conference-Proceedings.pdfhttps://sites.unica.it/rinem2018/
