The book reveals the reason why cryogenic refrigeration receiving technology can achieve high-sensitivity reception by introducing the composition of the cryogenic refrigeration receiving front-end and the design of core components such as low-noise amplifiers and superconducting filters. The book consists of seven chapters, which comprehensively discuss cryogenic receiving technology from the perspectives of system noise concepts, composition of cryogenic receiving frontends, design of core components such as cryogenic amplifiers, and low-noise measurement.

Chapter 1 introduces the development history of cryogenic receiving technology. Chapter 2 presents the basic concepts of low-noise technology. Chapter 3 focuses on the composition and key technologies of S/X/Ka-band cryogenic receiving frontends for deep-space stations. Chapters 4, 5, and 6 discuss the design of cryogenic amplifiers, superconducting filters, and cryogenic isolators respectively. Chapter 7 highlights low-noise measurement techniques.

This book is intended for designers and practitioners in the fields of communication systems, radio astronomy, and space research.
