【摘要】：随着微波通信系统的快速发展、计算机运算速度的提高和基础工业技术的发展,相控阵技术优势凸显。比如军事方面的相控阵雷达,民用领域新一代无线通信中的电调天线。在这些相控阵技术的应用中馈线承担着电扫描、多波束、副瓣电平控制等功能。这些微波组件对提高射频信号传输质量,提升整机系统信号传输、简化整机结构意义重大,同时对馈线的信号传输质量多了幅相一致性和相位稳定性的要求,射频稳相电缆技术也就应运而生。就射频电缆组件来说,要面临已然不是连接器和电缆的简单选型及其装配的问题,更是低驻波比、低损耗、稳相等方面的挑战。射频稳相电缆组件在开发过程中存在许多问题：稳相连接器和稳相电缆测设计或选型,及其匹配。本文针对这些问题,根据传输线理论,提出一个系统的开发方案。重点研究一下三个部分的主要内容：1、射频稳相电缆组件的组成。阐述射频稳相电缆组件在系统中的功能,并从微波传输线理论出发,根据系统对此射频稳相电缆组件的参数要求,谨慎选取射频稳相连接器和稳相电缆。2、稳相电缆组件装配工艺。根据稳相连接器的结构和稳相电缆的特点,在组件装配时选择适当的工艺方法、精准的工艺参数。3.射频稳相电缆组件装配过程中的相位控制。基于以上所有的研究结果,针对射频稳相电缆组件在装配过程中的种种问题,给出了解决方案,并展望了今后的发展方向。
[Abstract]:With the rapid development of microwave communication system development, improve the computing speed and the foundation of the industrial technology, highlighting the advantages of phased array technology. For example, the military aspects of the phased array radar, electrically adjustable antenna fields a new generation of wireless communication. In the phased array technology used in feeder undertakes electrical scanning, multi beam, side lobe the level control functions. The microwave module to improve the RF signal transmission quality, improve the signal transmission system, simplify the structure of great significance, at the same time, the quality of signal transmission on feeder more amplitude phase consistency and phase stability requirements, RF cable technology came into being. RF cable assembly, simple face the selection and assembly problem is already not the connectors and cables, is low in Bobbi, low loss, stable equal challenges. The RF cable assembly in the open There are many problems in the process of development: stationary phase and stationary phase measuring cable connector design or selection and matching. Aiming at these problems, according to the transmission line theory, put forward the development scheme of a system. It focuses on the main contents of three parts: 1, RF cable assembly. This function of RF cable components in the system, and based on the theory of microwave transmission line, according to the requirements of this system parameters of RF cable assemblies, careful selection of RF connector and cable stationary phase.2, phase stable cable assembly process. According to the characteristics of structure and stability of stationary phase phase cable connector, appropriate technology the choice in the assembly, the phase parameters of.3. RF precise phase stable cable assembly process control. All of the above research results based on the RF cable assembly in the assembly process The problems and solutions are given, and the future development direction.
