Broadband 230GHz finline mixer for astronomical imaging arrays
The authors report the successful operation of an antipodal finline quasi-particle SIS mixer at 230GHz. The mixer is fed by a waveguide diagonal horn and uses planar circuit technology and integrated tuning. The mixer is testd over the frequency range 213-265GHz and a receiver noise temperature of ≃...
