High-temperature superconducting transceiver subsystem

Abstract

The invention discloses a high-temperature superconducting transceiver subsystem which is packaged in a refrigerating machine in vacuum to keep operating temperature to be lower than transformation temperature of a superconducting material. The system comprises three radio frequency ports, a high-power superconducting filter, a circulator and a receiving channel. The system is applied to a wireless system for transmitting / receiving a wireless signal by a transmitter and a receiver respectively, thus achieving the purpose of receiving and transmitting the wireless signal simultaneously.

Description

technical field [0001] The invention relates to the field of wireless systems, in particular to a high-temperature superconducting transceiver 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 functio...
