Problems solved by technology

[0006] (3) The superconducting filter components of each channel need to be manufactured through one process, the production efficiency is low, and the performance consistency between the channels is poor
[0007] (4) Each superconducting filter and low-noise amplifier (LNA) requires an independent shielding box. Multiple shielding boxes make the weight, volume and thermal power consumption of the superconducting filter components large, which limits all components in a refrigerator. The number of superconducting filter channels that can be integrated

Description

technical field [0001] The invention belongs to the technical field of superconducting filters, in particular to a highly integrated multi-channel superconducting filter component. Background technique [0002] Superconducting filter components are composed of superconducting filter and low noise amplifier (LNA), which is one of the important application fields of superconducting materials. Superconducting filter components have extremely low noise figure, high band edge steepness, and good out-of-band rejection. Applying them to the receiver front-end of various microwave communication equipment can greatly improve the sensitivity and selection of the entire system Therefore, it has broad application prospects and huge market potential in microwave communication fields such as mobile communication, military communication, and satellite communication. [0003] Modern receivers require that the RF front-end has multiple signal channels, which requires the integration of mult...
