Abstract :
Compact mm/submm integrated spectrometers are required for radio-astronomical research, remote monitoring of the Earth atmosphere and environmental monitoring for hazardous materials of chemical and biological origin. Assembled on a multi-chip module the all superconducting integrated spectrometer offers integration of thin film analog components such as a mixer, superconducting local oscillator and an intermediate frequency SQUID amplifier together with superconducting digital circuitry. A Rapid Single Flux Quantum (RSFQ) 128-bit autocorrelator formed by 16-bit autocorrelator and a 112-bit programmable shift register that adjusts the data delay in increments of 16, is used for digitizing of the down converted signals and real-time digital processing. Experimental results showing both operation of components and the way to their successful integration are presented.
