Applications of high-temperature-superconducting filters and cryoelectronics for satellite communication

摘要

Filtering of the signals from satellites in ground-based satellite-communication receivers using high-temperature superconducting filters will be discussed in this paper, including the use of cryogenically cooled low-noise amplifiers and cooled RF switches. In addition to the RF circuits, a detailed discussion of the needed support, such as cryocoolers and Dewar, will be held. Uses for the system will be discussed and a demonstration described.
