“…The mixers are reduced-height waveguide mixers with a single, adjustable, non-contacting backshort (Blundell et al 1988;Karpov et al 1998). The current mixing elements are SIS double junctions in Nb technology with individual integrated parallel tuning.…”

Abstract. We describe the technical concept, properties, and performance of HERA (HEterodyne Receiver Array) at the IRAM 30 m telescope. HERA is a multibeam, waveguide SIS receiver that greatly improves mapping speed in various observing modes and also provides possibilities for new high-sensitivity observing of small sources. Future extensions with a second polarization module will permit spectro-polarimetry. We present some examples of astronomical maps with HERA.

“…At about the same time, a comprehensive theoretical investigation of the SIS made clear that SIS's respond to photons at millimeter and submillimeter wavelengths [3]. The SIS has become the instrument of choice for millimeter spectroscopic radio astronomy, finding use on radio telescopes around the world [4][5][6][7][8][9][10][11][12][13].…”

Superconductor-Insulator-Superconductor (SIS) diodes are the detector elements in the most sensitive heterodyne receivers available from 100 to 500 GHz. SIS mixers are the front end of radio astronomical systems around the world. SIS mixer technology is being extended to 1 THz and higher frequencies for eventual use on spaceborne astronomical experiments.Here is a short review of submillimeter SIS mixers. The role of impedance matching in the proper design of an SIS mixer is described. A variety of methods for achieving good impedance match at submillimeter frequencies are presented. The experimental state of the submillimeter SIS jnixer art is described and summarized.

“…Soon after the first mixing experiments were reported in 1979, SIS quasiparticle mixers began to replace Schottky diode mixers in coherent receivers for molecular line radio astronomy [21][22][23]. These receivers are now in daily use on millimeter wave telescopes and interferometers in at least ·six observatories.…”

“…Waveguide SIS.mixers have been constructed at frequencies up to 345 GHz by several groups [13,14,23,27,29,30]. Because of increased waveguide loss and increased difficulty of fabricating precise structures for these frequencies, As is shown in Fig.…”
