Abstract
- We describe in detail the principles of designing a tunable mixer with suppression of the mirror channel for the frequency band 86-115 GHz and a mixer for the band 787-950 GHz with twochannel reception and absence of the mechanical-tuning components. The mixers are based on superconductor-insulator-superconductor tunnel superconducting junctions with normal metal (aluminum) in the tuning circuit. The two developed mixers are optimized for the one-side chip connection to the full-height rectangular waveguide, which is required for creating a submillimeterwave single-chamber balanced waveguide mixer with a wide intermediate frequency bandwidth. The input-signal reflection coefficient is below −15 dB and the loss of the signal transmission to the mixer is below 3 dB in the frequency band 787-950 GHz. [ABSTRACT FROM AUTHOR]
