报告摘要

High-temperature superconducting (HTS) technologies have many potential applications, such as power transmission, medical imaging, quantum computing, military and aerospace, etc., due to their significant advantages of high energy efficiency, easy cooling as well as high reliability and stability. High-temperature superconducting technologies also play a critical role in wireless communications as they are offer unique advantages for applications in high-frequency electromagnetic domains. High-sensitivity and broadband nature of superconducting devices can be applied for high-speed wireless communication systems, especially the heterodyne mixers are highly desirable for high-gain and low-noise RF receivers. This talk will introduce a series of monolithic microwave integrated circuits (MMICs), mainly heterodyne mixers and on-chip antennas, which are used in microwave and millimeter-wave RF receivers. The MMIC mixers aredeveloped based on the quantum tunnelling effect of Josephson junctions and will signifcantly reduce the power consumption and enhance the sensitivity of RF receivers. Besides, advanced antenna technologies, including the packaging techniques of a high-gain waveguide antenna with MMIC's and a frequency-scanning leaky-wave antenna, will also be touched in this talk.
