Abstract

In this paper, a novel design structure of a dual-band filter is proposed. The core of the structure is to form a dual-band filter by connecting two sub-filters through a matching network. The matching network can not only improve the flexibility of the design, but also minimize the influence between the two sub-filters. Two sub-filters are designed separately, one of which is composed of interdigital resonators and the other is composed of hairpin resonators. The center frequency and bandwidth of the two passbands are flexible and controllable. Finally, a dual-band high-temperature superconducting (HTS) filter is designed and successfully fabricated on a DyBa₂Cu₃O₇ (DyBCO) thin film on thickness of 0.5 mm LaAlO₃ wafer, and the measured results are in good agreement with the simulation results.

设计和开发具有新型结构的双频超导滤波器

本文提出了一种新颖的双频滤波器设计结构。该结构的核心是通过匹配网络连接两个子滤波器，形成双频滤波器。匹配网络不仅能提高设计的灵活性，还能将两个子滤波器之间的影响降至最低。我们分别设计了两个子滤波器，其中一个由数字间谐振器组成，另一个由发夹谐振器组成。两个通带的中心频率和带宽是灵活可控的。最后，在厚度为 0.5 mm LaAlO3 晶圆上的 DyBa2Cu3O7（DyBCO）薄膜上设计并成功制作了双频高温超导（HTS）滤波器，测量结果与模拟结果非常吻合。

期刊介绍： Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity. The main goal of the journal is to publish: 1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods. 2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance. 3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices. The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
