Abstract:
The Atacama Large Millimeter Array (ALMA) requires low noise SIS receivers for frequencies from about 80 GHz to 950 GHz with very large IF bandwidth (4-12 GHz). Additional requirements for these receivers are high reliability, low cost and the possibility of series production. In this paper we report on mixer designs based on standard Nb/A10x/Nb SIS junction technology and an optics design for ALMA band 9 (602 — 720 GHz). We present the design of a tunerless balanced waveguide SIS mixer and a quasi-optical double slot-antenna mixer as well as an optical design to couple the telescope beam to the mixer. The waveguide balanced mixer is based on a magic T with integrated RF and LO feed horns.
