Microwave filters using high-temperature superconductors
C.G. Li, Chinese Academy of Sciences, China
This chapter discusses the applications of high-temperature superconductors (HTS) in microwave technology, particularly microwave filters. The chapter first reviews some fundamental aspects of how superconductors interact with high-frequency fields and then briefly outlines their basic elements: superconducting microwave transmission lines and related passive devices. The design and construction of superconducting filters and microwave receiver front-end subsystems will be discussed in detail. Finally the world’s first superconducting meteorological radar will be introduced as a successful application example of ...
