【摘要】：毫米波射频同轴连接器是用于毫米波系统间信号连接的重要元器件。近年来,随着毫米波系统的技术发展,以往用矩形或圆形波导进行毫米波连接的方式已经越来越不适应毫米波系统逐渐小型化的趋势。如今的毫米波系统需要在有限的空间实现多路信号互联,同时要求盲插和快速装卸,波导的安装方式已经无法满足这种技术要求,于是毫米波射频同轴连接器的应用逐步走上正轨,而且越来越多的军事武器装备系统对其的需求量稳步增长。国内毫米波射频同轴连接器的研究起步较晚,与国外技术水平差距较大,目前国内上机使用的毫米波射频同轴连接基本依靠进口,武器装备研制过程受制于人的局面非常严峻。为了实现关键元器件“自主可控”的战略目标,高端毫米波射频同轴连接器国产化研制的工作十分必要。本文首先介绍了毫米波射频同轴连接及其应用领域,特别对其实际应用场合进行了调研和总结,为本课题研究成果的应用奠定了基础,指明了方向。同时,本文还对毫米波射频同轴连接器的国内外技术水平的差距和技术总体发展趋势进行了分析和论述,以便于对本课题研究成果进行定位,并在后续的课题研究工作中找准着力点。接着,文章从基本理论入手,研究了毫米波射频同轴连接的设计方法和关键技术,然后再分别以40GHz毫米波射频同轴连接器和65GHz毫米波射频同轴连接器的设计过程为例进行了毫米波射频同轴连接器设计技术的实践,特别是对关键零件——绝缘子的结构设计以及调整方法进行详细论述和分析。将理论研究的成果应用于具体设计,在完成40GHz毫米波射频同轴连接器优化设计的基础上落实了65GHz毫米波射频同轴连接器的设计方案,并通过产品试制完成了设计方案的验证,实现了国产化。产品实物经实际测试,65GHz毫米波射频同轴连接器产品性能已基本达到国外同类产品水平。本文的研究成果从理论分析出发,经过了实践的检验,符合较高频段毫米波射频同轴连接器设计的技术要求。根据本文的研究成果不但可以成功研制出SMPM型65GHz毫米波射频同轴连接器,还可以举一反三,将其优化分析的设计方法推广到其他类别的毫米波射频同轴连接器。
[Abstract]:Millimeter-wave RF coaxial connector is an important component for signal connection between millimeter-wave systems. In recent years, with the development of millimeter-wave system technology, In the past, millimeter-wave connections using rectangular or circular waveguides have become less and less suitable for the gradual miniaturization of millimeter-wave systems. Today's millimeter-wave systems need to realize multi-channel signal interconnection in limited space. At the same time, blind insertion and fast loading and unloading are required. The installation of the waveguide can no longer meet this technical requirement, so the application of millimeter-wave RF coaxial connectors is gradually on the right track. Moreover, more and more military weapon systems have a steady increase in demand. The research of millimeter-wave RF coaxial connectors in China started relatively late, and there is a big gap between the domestic and foreign technology levels. At present, the millimeter-wave RF coaxial connection used on the domestic computer basically depends on imports, and the development process of weapons and equipment is controlled by people. In order to achieve the strategic goal of "autonomous and controllable" key components, It is necessary to develop high-end millimeter-wave RF coaxial connectors at home. Firstly, this paper introduces millimeter-wave RF coaxial connections and their application fields. This paper lays a foundation for the application of the research results and points out the direction. At the same time, this paper also analyzes and discusses the gap between domestic and foreign technology level and the overall development trend of millimeter-wave RF coaxial connectors. In order to locate the research results of this subject, and to find the point of focus in the following research work, this paper studies the design method and key technology of millimeter wave RF coaxial connection from the basic theory. Then taking the design process of 40GHz millimeter wave radio frequency coaxial connector and 65GHz millimeter wave radio frequency coaxial connector for example, the design technology of millimeter wave radio frequency coaxial connector is put into practice. In particular, the structural design and adjustment method of the key part-insulator are discussed and analyzed in detail. The results of theoretical research are applied to the specific design. On the basis of the optimization design of 40GHz millimeter wave RF coaxial connector, the design scheme of 65GHz millimeter wave RF coaxial connector is implemented, and the design scheme is verified by the product trial manufacture. The performance of the product has basically reached the level of the same kind of foreign products. The research results of this paper are based on the theoretical analysis, and have been verified by practice. It meets the technical requirements of the design of millimeter wave RF coaxial connectors in high frequency band. According to the research results of this paper, not only the SMPM type 65GHz millimeter wave RF coaxial connectors can be successfully developed, but also the same thing can be done. The design method of optimization analysis is extended to other kinds of millimeter wave RF coaxial connectors.
