【摘要】：毫米波位于微波和红外线之间,具有两种频谱的特点。首先,毫米波的波长非常短,电离层穿透性强,非常适合卫星通信。其次,频带非常宽,具有丰富的频谱资源可以利用。最后,毫米波与大气的相互作用明显,能够应用于保密通信。基于上述特点,毫米波的前景非常广阔,世界各国都已开展相关研究,毫米波通信是未来发展的必然趋势。本课题研制了W波段平面混合集成收发前端,工作频率为94GHz,带宽3GHz,位于毫米波的第二个大气窗口。该收发前端是由多个功能模块级联而成,包含毫米波模块和微波模块两大部分,最终将整个收发前端装配在了一个机箱中,使用非常方便。本文的主要工作为:1、简要介绍下毫米波的研究背景及意义,然后列举了一些国内和国外的发展动态,为本课题的研究提供参考价值。2、阐述了几种常用的发射机和接收机架构,根据本课题的指标要求、设计难度和复杂度,选择适合本课题的收发机架构。3、确定收发机总体架构后,接下来就是根据收发前端的指标要求为每个功能模块合理的分配指标,并开始对各个单元模块进行设计。4、首先详细分析了毫米波模块中三个模块的主要技术指标、具体方案、设计方法、单片选取以及调试与测试。讲述了设计和调试过程中需要注意的细节和调试时遇到的问题及解决方法。然后着重分析了微波模块中各单元子模块的主要技术指标、实施方案、实现方法和测试结果,并详细分析了各模块的性能是否会对整个收发前端产生影响,为最终的系统级联工作打下基础。5、当所有模块都设计和调试完成后,就开始进行级联工作,测试整个收发前端级联后的工作性能,并最终装配在设计好的机箱中。6、针对整个收发前端研制过程中的一些不足之处,提出了改进意见。
[Abstract]:Millimeter wave is located between microwave and infrared, and has two kinds of spectrum characteristics. First of all, millimeter-wave wavelength is very short, ionospheric penetration is strong, very suitable for satellite communications. Second, the frequency band is very wide, with rich spectrum resources can be used. Finally, the interaction between millimeter wave and atmosphere is obvious and can be applied to secure communication. Based on the above characteristics, the prospect of millimeter wave is very broad, and the related research has been carried out all over the world. Millimeter wave communication is an inevitable trend in the future. In this paper, the W band plane hybrid integrated transceiver front end is developed. The working frequency is 94 GHz and the bandwidth is 3 GHz, which is located in the second atmospheric window of millimeter wave. The transceiver front-end is composed of several function modules, including millimeter wave module and microwave module. Finally, the whole transceiver front-end is assembled in a chassis, which is very convenient to use. The main work of this paper is: 1: 1. The background and significance of millimeter wave research are briefly introduced, and then some domestic and foreign developments are listed, which provide reference value for the research of this subject, and several commonly used transmitter and receiver architectures are expounded. According to the index requirements, design difficulty and complexity of this subject, select the transceiver architecture. 3, determine the overall structure of the transceiver, then according to the requirements of the transceiver front-end index for each functional module reasonable allocation index. And begin to design each unit module. Firstly, the main technical index, specific scheme, design method, single chip selection, debugging and testing of the three modules in the millimeter wave module are analyzed in detail. The details of the design and debugging process, the problems encountered in debugging and the solutions are described. Then, the main technical index, implementation scheme, implementation method and test results of each unit sub-module in microwave module are analyzed in detail, and whether the performance of each module will affect the whole transceiver front end is analyzed in detail. Lay the foundation for the final system cascade work. When all the modules are designed and debugged, the cascade work begins to test the performance of the whole transceiver front-end cascade. Finally, it is assembled in the designed crate. 6. Aiming at some shortcomings in the whole development process of the transceiver front end, the improvement suggestions are put forward.
