Versatile Radiometric Testbed for the Submillimeter Wave Instrument

• This paper presents a radiometric testbed for the characterization of the 600-GHz and 1200-GHz double side band heterodyne receivers of the Submillimeter Wave Instrument on the Juice mission of ESA. The testbed enables measurements of receiver noise temperature, gain stability, side band ratio, and beam coalignment in a thermal-vacuum chamber. Receiver spectral response and spurious signal investigations are possible with an optional transmitter. Measurement results obtained for engineering and protoflight models of the instrument are presented.
