Description

technical field [0001] The invention relates to a superconducting receiving system, in particular to a high-efficiency integrated superconducting receiving system for a communication base station, which is suitable for improving the receiving sensitivity and noise figure of the communication base station. Background technique [0002] Due to the wider frequency bandwidth used by the third-generation mobile communication standard, services such as voice calls, text messages, images, and videos have been expanded, and the amount of information transmitted has increased. With the commercialization of 4G, the amount of information transmission will further increase. Therefore, the requirements for the comprehensive technical indicators of the front-end reception are higher, and the front-end reception is required not only to have a high edge steepness, but also to have a good linear phase characteristic. The traditional approach is to use a cavity receiver at the input of the ba...

AI Technical Summary

Problems solved by technology

At present, the superconducting receiving technology is applied to the communication base station. Generally, the superconducting receiving front-end device is connected in front of the radio frequency processing unit of each sector, and the signal is separated and transferred before connecting to each signal channel. There are many types of equipment, and Grid connection is complex

At the same time, since the superconducting filter device is affected by the transition temperature, once the front-end device fails, the base station maintenance background needs to analyze the data to know the cause of the failure, resulting in a delay in failure analysis and judgment, so its reliability is low
