We have designed and constructed a Fourier Transform Spectrometer (FTS) for the study of submillimeter-wave mixers and optical components. The FTS has a large aperture (up to 25.4 cm) and small focal ratio (as fast as f/2.5) to achieve a large throughput. It operates in the 100-3750 GHz (3.3125 cm 1) frequency range with a resolution of up to 75 MHz (0.0025(More)
AbstructWe report on the development of low-noise quasioptical SIS mixers for the frequency range 400-850 GHz. The mixers utilize twin-slot antennas, two-junction tuning circuits, and Nb-trilayer junctions. Fourier-transform spectrometry has been used to verify that the frequency response of the devices is well predicted by computer simulations. The 400-850(More)

A new method is introduced in GPRS data transmission control system design, which is to employ two microcontrollers as control core. Firstly introduced the GPRS data transmission system, and then gave a new GPRS data transmission control system hardware schematic design and software flow chart design. Compared to systems using single microcontroller, ARM or(More)
We recently reported [SI a quasi-optical SIS mixer which used Nb/Al-oxide/Nb tunnel junctions and a normal-metal (Al) tuning circuit to achieve an uncorrected receiver noise temperature of 840 K (DSB) at 1042 GHz. Were we present results on several different device designs, which together cover the 300 1200 GHz frequency range. The mixers utilize an(More)
