【摘要】：在毫米波電路與系統(tǒng)中,處于毫米波系統(tǒng)關(guān)鍵地位的接收前端對系統(tǒng)的性能起著至關(guān)重要的作用。鑒于毫米波技術(shù)在現(xiàn)代軍事、通信等領(lǐng)域日漸深入地應(yīng)用,對毫米波關(guān)鍵技術(shù)的研究就顯得越加迫切。然而目前國內(nèi)對高頻段尤其是3mm波段電路與系統(tǒng)的研究和報道都比較少。本課題的任務(wù)就是對3mm接收前端的理論和設(shè)計方法進行研究。本文所設(shè)計的3mm接收前端系統(tǒng)用于雷達接收機,采用本振端固定點頻的超外差式接收結(jié)構(gòu)設(shè)計,用混合集成電路方式實現(xiàn)。該接收前端包括兩條接收支路,每條接收鏈路由過渡、低噪聲放大器、混頻器、濾波器等組件組成。根據(jù)項目的研究目標和指標要求,論文詳細地分析了3mm接收機前端系統(tǒng)的整體設(shè)計方案,并對其中各子電路進行了指標細化、分配和估算。重點研究了接收支路中過渡單元、濾波電路、低噪聲放大器、混頻器的基本理論和設(shè)計方法,并對各單元組件進行了仿真設(shè)計,尤其就對系統(tǒng)性能影響較大的部分關(guān)鍵組件進行了單獨加工與實測。結(jié)合設(shè)計的無源組件與選取的固態(tài)單片,對接收支路進行了電路布局以及腔體結(jié)構(gòu)的設(shè)計。最終完成系統(tǒng)的性能參數(shù)估算和測試,結(jié)果顯示各項指標基本達到項目指標要求。最后,總結(jié)了本文主要的研究內(nèi)容并得出結(jié)論,給出后續(xù)工作可以加強和改進的方向。本論文所進行的工作在一定程度上為今后毫米波接收前端技術(shù)領(lǐng)域的研究提供了相關(guān)經(jīng)驗。
[Abstract]:In millimeter-wave circuits and systems, the front-end in the key position of millimeter-wave system plays an important role in the performance of the system. The research on the key technology of millimeter wave is more and more urgent. However, there are few researches and reports on the circuits and systems in the high frequency band, especially in the 3mm band. The task of this subject is to study the 3mm receiver front end. The 3mm receiver front-end system designed in this paper is used for radar receiver. The superheterodyne receiving structure with fixed point frequency at the local oscillator end is designed and realized by hybrid integrated circuit. The front end of the receiver includes two receiving branches, each receiving link is transitioned, low noise amplifier, mixer. Filter and other components. According to the research objectives and requirements of the project, the paper analyzes the overall design scheme of the 3mm receiver front-end system in detail, and the sub-circuits are refined. Distribution and estimation. The basic theory and design method of transition unit, filter circuit, low noise amplifier and mixer in the receiving branch are studied, and each unit module is simulated and designed. In particular, some key components which have a great impact on the system performance have been processed and measured separately, combined with the design of passive components and the selection of solid state monolithic. The circuit layout and cavity structure of the receiving branch are designed. Finally, the performance parameters of the system are estimated and tested. The results show that the indicators basically meet the requirements of the project. Finally. This paper summarizes the main research content and draws a conclusion. The future work can be strengthened and improved. To a certain extent, the work carried out in this paper provides relevant experience for the research of millimeter-wave receiver front-end technology in the future.
