【摘要】：隨著微波通信系統(tǒng)的快速發(fā)展、計算機(jī)運(yùn)算速度的提高和基礎(chǔ)工業(yè)技術(shù)的發(fā)展,相控陣技術(shù)優(yōu)勢凸顯。比如軍事方面的相控陣?yán)走_(dá),民用領(lǐng)域新一代無線通信中的電調(diào)天線。在這些相控陣技術(shù)的應(yīng)用中饋線承擔(dān)著電掃描、多波束、副瓣電平控制等功能。這些微波組件對提高射頻信號傳輸質(zhì)量,提升整機(jī)系統(tǒng)信號傳輸、簡化整機(jī)結(jié)構(gòu)意義重大,同時對饋線的信號傳輸質(zhì)量多了幅相一致性和相位穩(wěn)定性的要求,射頻穩(wěn)相電纜技術(shù)也就應(yīng)運(yùn)而生。就射頻電纜組件來說,要面臨已然不是連接器和電纜的簡單選型及其裝配的問題,更是低駐波比、低損耗、穩(wěn)相等方面的挑戰(zhàn)。射頻穩(wěn)相電纜組件在開發(fā)過程中存在許多問題：穩(wěn)相連接器和穩(wěn)相電纜測設(shè)計或選型,及其匹配。本文針對這些問題,根據(jù)傳輸線理論,提出一個系統(tǒng)的開發(fā)方案。重點(diǎn)研究一下三個部分的主要內(nèi)容：1、射頻穩(wěn)相電纜組件的組成。闡述射頻穩(wěn)相電纜組件在系統(tǒng)中的功能,并從微波傳輸線理論出發(fā),根據(jù)系統(tǒng)對此射頻穩(wěn)相電纜組件的參數(shù)要求,謹(jǐn)慎選取射頻穩(wěn)相連接器和穩(wěn)相電纜。2、穩(wěn)相電纜組件裝配工藝。根據(jù)穩(wěn)相連接器的結(jié)構(gòu)和穩(wěn)相電纜的特點(diǎn),在組件裝配時選擇適當(dāng)?shù)墓に嚪椒ā⒕珳?zhǔn)的工藝參數(shù)。3.射頻穩(wěn)相電纜組件裝配過程中的相位控制�；谝陨纤械难芯拷Y(jié)果,針對射頻穩(wěn)相電纜組件在裝配過程中的種種問題,給出了解決方案,并展望了今后的發(fā)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.
