Abstract :
A fully integrated, low-noise, SIS mixer for 75-110 GHz with no adjustable tuners is demonstrated. The unexpectedly large conversion loss of the mixers has not yet been explained. Simple coplanar topology is used. This eliminates the need for registering patterns on opposite sides of a wafer, and allows the use of a conveniently thick substrate (0.010 in) in the mixer. The design is readily integrable with other components, such as planar antennas or future superconducting IF processors. The design should be useful up to 300 GHz, and possibly to 600 GHz, with appropriate frequency scaling.<>
