Abstract :
A millimeter-wave communication system incorporating with a 100-GHz superconducting SIS (superconductor-insulator-superconductor) receiver is demonstrated. The SIS receiver has an intermediate frequency (IF) band of 1.1-1.7 GHz and an equivalent input noise temperature less than 50 K, while the transmitter is a 93-GHz varactor-tunable Gunn oscillator with its output frequency modulated via an 11-MHz signal source. In addition, two analog FM demodulation techniques are adopted in this experiment.
