متن کاملCoherent Detection and Sis Mixers
Submillimeter spectroscopy is a unique and very rich source of astrophysical information. While many important results have been obtained using ground based telescopes, the Kuiper Airborne Observatory, ISO, and SWAS, this field will soon experience rapid growth and development due to projects such as SOFIA, ALMA, and the Herschel Space Observatory (HSO). High spectral resolution is and will con...
متن کاملImage-Reject and Single-Sideband Mixers
Image-reject mixers (IRMs) and single-sideband mixers (SSMs) play a key role in many of today’s microwave and rf systems [1, 2, 3]. IRMs and SSMs reduce system cost and complexity by removing the need for expensive preselection, and one or more stages of upor downconversion. IRMs simplify downconversion by employing phase-cancellation techniques to separate the downconverted products resulting ...
متن کاملCharacterization of submillimetre quasi-optical twin-slot double-junction SIS mixers
We report on the continuing development of submillimetre quasi-optical slot antenna SIS mixers, which use two-junction tuning circuits. Direct and heterodyne Fourier transform spectrometer measurements have been performed to compare device performance with predictions. Demonstrated double-sideband receiver noise temperatures of better than 540 K at 808 GHz make these SIS mixers substantially be...
متن کاملLow-noise submillimeter-wave NbTiN superconducting tunnel junction mixers
We have developed a low-noise 850 GHz superconductor–insulator–superconductor quasiparticle mixer with NbTiN thin-film microstrip tuning circuits and hybrid Nb/AlN/NbTiN tunnel junctions. The mixer uses a quasioptical configuration with a planar twin-slot antenna feeding a two-junction tuning circuit. At 798 GHz, we measured an uncorrected double-sideband receiver noise temperature of TRX5260 K...
