摘要
本论文来源于电子科技大学微波中心向四川省青年科学基金申请的“高性能高温超导移动通信基站接收前端技术的研究”。
利用高温超导(HTSC)薄膜材料研制的移动通信基站接收前端具有插损极小、噪声极低、带外抑制陡峭等显著优点,是利用波导腔、介质谐振器或常规的平面结构设计的基站接收前端所无法比拟的。利用高性能高温超导滤波器(HTSBPF)和工作在液氮温区的(77K)的低噪声放大器(LNA)来改进移动通信基站接收前端的工作,可对接收机的灵敏度和抗干扰特性具有明显改善。本文介绍了高温超导材料的基本特性,对高性能高温超导基站接收前端进行了分析,给出了高温超导滤波器的设计原理,并综合设计了符合要求的高温超导基站接收前端。本文解决了高温超导高性能滤波器的设计、密封封装和低温测量等难点,成功地在LaALO3 基片上设计并制作了中心频率0.795GHZ,带宽22MHz 的12 级高温超导带通滤波器并以此滤波器为核心集成的高温超导基站接收前端子系统,该子系统总噪声系数〈0.90dB ,带外抑制〉60dB,接收通道滤波器矩形系数约为1.4(60dB 带宽/1dB 带宽),满足设计要求。
This paper is rooted from the fund of “The study of high-temperature supercon-ductor receiver front-end with high performances for motion communications ”. The micro-wave receiver front-end using HTSC thin films that are mass have the advantages of low resistance and high quality factor, so it’s performances are much better than the receiver front-end using wave-guide 、medium resonance or conventional planar structures, offers the potential of large reduction in mass and volume of receiver systems, and lead to significant cost reduction of space systems. By using high temperature HTSC film,we have developed narrowband low insertion loss bandpass,developed low noise amplifier LNA with 0.5dB NF working in 77K liquid Nitrogen temperature.This paper presents the characteristics of HTSC materials and the theory of HTSC receiver front-end. The modes of HTSC resonance and receiver front-end were built using CAD programs by full-wave field solvers. Then the HTSC receiver front-end according to the aim of designs were synthesized, manufactured, installed and measured. In this paper, a series of difficulties such as the precision of design、the lithography process technology、the encapsulation and the measurement in low temperature and so on were solved, receiver front-end having a bandwidth of 22MHz, having center frequencies in 0.795GHz with 0.90 dB NF and restraint restrain besides passband greater than 60dB was designed, 1.4 of rectangle coefficient of receive bandpass filter and measurement results satisfied the requires of designs.
