1Development of miniature HTSC wide-band filter with open-loop resonators显示文摘The strong electric and magnetic coupled novel HTSC (high temperature superconductor) open-loop microstrip resonators are studied in this report and the traditional structure of open-loop resonators is improved. A miniature wide-band HTSC bandpass filter is developed by the novel structure, which is fabricated on YBCO/LaAlO3/YBCO substrate with dimensions of 14.8×9.6 mm2. This filter is tested at 77 K, and the specifications are that the center frequency is 2230 MHz, the bandwidth is 455 MHz, and the best insertion loss is 0.14 dB in passband.ZHANG TianLiang YANG Kai NING JunSong BU ShiRong LIU JuanXiu LUO ZhengXiang 2008Chinese Science Bulletin2008,53,9:5
2限幅自保护高温超导接收机前端研究显示文摘提出了一种新型的、具有限幅自保护功能的新型高温超导高性能接收机前端系统方案。采用将高温超导限幅滤波器前置于低噪放进行混合集成,利用高温超导限幅滤波器优异的滤波和限幅特性实现同时具有高灵敏度和自保护功能的接收机前端。实验结果表明该滤波器可以有效地保护后端的低噪放不被烧毁或阻塞。采用超导-常规电路混合集成工艺研制而成的限幅自保护高温超导接收机前端具有优异的接收灵敏度,总噪声系数小于0.7dB。羊恺 补世荣 刘娟秀 罗正祥 2007电子科技大学学报2007,36,2:3
3Investigation of HTSC digital trunking communication receiver subsystem显示文摘The application of HTSC (high temperature superconductor) microwave devices in a UHF digital trunking communication system is introduced.The replacement between the HTSC microwave devices and the normal microwave devices is conducted.The digital sensitivity of the base station in complex electromagnetic environment has been increased to 6 dB,as the results of the experiment indicated,and this means that the coverage radius of the base station has been improved about twice,that is to say,the coverage area can be extended to four times as large as that of the current method.YANG Kai LAI JinMing BU ShiRong ZENG Cheng ZOU XiongFei 2010Chinese Science Bulletin2010,55,12:1
4一种基于三角形耦合环的可调同轴腔滤波器显示文摘提出并研究了一种用于小型化同轴腔可调带通滤波器的新型腔间耦合结构,这种结构可使滤波器绝对带宽在工作频率范围内几乎保持常数。新型腔间耦合结构由三角形耦合环和矩形耦合窗复合组成,它能在保持腔间耦合度的情况下控制腔间耦合带宽随工作频率的变化,从而使可调滤波器在工作频段内的高低端绝对带宽保持不变。文中在分析同轴腔内电磁场分布的基础上得出了带宽恒定条件下的结构参数约束范围。采用这种耦合结构设计并制作的3腔同轴腔可调滤波器得到了56%的调谐范围和小于±3%的带宽差。张忠海 官伯然 2010微波学报2010,26,5:0
