【摘要】：毫米波位于微波和紅外線之間,具有兩種頻譜的特點。首先,毫米波的波長非常短,電離層穿透性強,非常適合衛(wèi)星通信。其次,頻帶非常寬,具有豐富的頻譜資源可以利用。最后,毫米波與大氣的相互作用明顯,能夠應用于保密通信�；谏鲜鎏攸c,毫米波的前景非常廣闊,世界各國都已開展相關研究,毫米波通信是未來發(fā)展的必然趨勢。本課題研制了W波段平面混合集成收發(fā)前端,工作頻率為94GHz,帶寬3GHz,位于毫米波的第二個大氣窗口。該收發(fā)前端是由多個功能模塊級聯(lián)而成,包含毫米波模塊和微波模塊兩大部分,最終將整個收發(fā)前端裝配在了一個機箱中,使用非常方便。本文的主要工作為:1、簡要介紹下毫米波的研究背景及意義,然后列舉了一些國內(nèi)和國外的發(fā)展動態(tài),為本課題的研究提供參考價值。2、闡述了幾種常用的發(fā)射機和接收機架構,根據(jù)本課題的指標要求、設計難度和復雜度,選擇適合本課題的收發(fā)機架構。3、確定收發(fā)機總體架構后,接下來就是根據(jù)收發(fā)前端的指標要求為每個功能模塊合理的分配指標,并開始對各個單元模塊進行設計。4、首先詳細分析了毫米波模塊中三個模塊的主要技術指標、具體方案、設計方法、單片選取以及調(diào)試與測試。講述了設計和調(diào)試過程中需要注意的細節(jié)和調(diào)試時遇到的問題及解決方法。然后著重分析了微波模塊中各單元子模塊的主要技術指標、實施方案、實現(xiàn)方法和測試結果,并詳細分析了各模塊的性能是否會對整個收發(fā)前端產(chǎn)生影響,為最終的系統(tǒng)級聯(lián)工作打下基礎。5、當所有模塊都設計和調(diào)試完成后,就開始進行級聯(lián)工作,測試整個收發(fā)前端級聯(lián)后的工作性能,并最終裝配在設計好的機箱中。6、針對整個收發(fā)前端研制過程中的一些不足之處,提出了改進意見。
[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.
