High-temperature superconducting duplex subsystem

Abstract

The invention discloses a high-temperature superconducting duplex subsystem which is packaged in a refrigerator in vacuum; and the operating temperature is kept to be lower than the transition temperature of a superconducting material. The high-temperature superconducting duplex subsystem comprises two radio frequency (RF) ports, a large-power superconducting filter, a first circulator, a second circulator, a receiving channel and a microwave element. The system is applied in a wireless system and can realize the situation of simultaneously receiving and sending wireless signals.

Description

technical field [0001] The invention relates to the field of wireless systems, in particular to a high-temperature superconducting duplex subsystem. Background technique [0002] With the rapid development of modern communication technology and the increasing scale of the communication market, the existing wireless spectrum is increasingly crowded. Spectrum resources occupied by various value-added communication services continue to extend to the high-end frequency. A severe and urgent issue facing radio engineers is: how to make the most effective use of existing spectrum resources. Therefore, in order to simplify spectrum resources, many wireless systems use the same wireless frequency band for receiving and transmitting signals, such as radar, TD-SCDMA, Wi-max, etc. [0003] The high-temperature superconducting filter is a microstrip filter made of high-temperature superconducting materials. The microstrip filter is a key device in a wireless system, and its function is ...
