【摘要】：高度信息化的社會,無時不刻地在改善人們的生存環(huán)境、生活方式。當前移動互聯(lián)僅用了短短幾年時間就得到廣泛應用,獨立移動性的信息服務成為當前服務行業(yè)的主流方向,帶給人們生活、工作等方面全方位的便利。在數(shù)據(jù)量越來越龐大的今天,作為信息服務的橋梁,無線通信面臨著前所未有的機會,但卻也是更加艱巨的挑戰(zhàn)。在無線系統(tǒng)中,濾波器、多工器是隔離、提取信號的關鍵組成部分,頻譜資源有限,為了實現(xiàn)盡量高的頻譜應用效率,無線頻帶的劃分要求更加精細。另外,電子行業(yè)的趨勢是微型化、低成本、集成化。因此,微型高性能濾波器的研制對當前以及未來無線通信的發(fā)展來說,顯得尤為迫切。傳統(tǒng)腔體、同軸和微帶傳輸線濾波器一般不能兼具上述性能,當前的濾波器設計,需要將經(jīng)典理論與工業(yè)工藝密切結合起來。隨著LTCC (Low Temperature Co-fired Ceramic)、LCP (Liquid Crystal Polymer)和HTCC (Low Temperature Co-fired Ceramic)工藝和基板材料尤其是陶瓷材料技術的發(fā)展,集成化微波無源、有源電路器件得到了良好的發(fā)展契機。雙模、多模諧振級結構以其優(yōu)異的電氣特性如可控的基模和高次模諧振頻率、與生俱來的微型化特性,在工程射頻微波濾波器的設計中得到了普遍應用。它的設計效率高且成本低,同時表現(xiàn)出了較好的性能。微型化是當前電子器件、集成電路等行業(yè)研究的焦點。在微波濾波器領域,常采用多模諧振技術、電容等效技術和階躍阻抗諧振技術來實現(xiàn)微型化。本文基于LTCC工藝,分析了大量前沿的微型多模濾波器的研究動態(tài)、應用的方法技術,多方面整合了雙模、多模諧振與階躍阻抗諧振特點,采用上述技術與LTCC多層工藝設計了四類結構共五種雙、多模諧振濾波器,包括窄帶濾波器,多級高性能雙模濾波器以及雙通帶濾波器,驗證了多模的靈活可控諧振特性。該五種濾波器結構簡單,設計步驟簡易,且性能良好。器件體積實現(xiàn)了微型化,五種濾波器體積主要分為兩種,分別是4.8mm×3.2mmx 1.5mm和9.12mmx4.2mm×1.5mm。上述五種濾波器可普遍應用于移動通信終端、基站、衛(wèi)星通信、軍用通信等對器件體積和性能要求高的場合。其中一種微型雙模高性能濾波器是與某國防研究所的合作項目,仿真結果完全滿足指標要求,現(xiàn)已進入后期加工階段。
[Abstract]:In a highly information society, people are constantly improving their living environment and way of life. At present, mobile interconnection has been widely used in only a few years, and independent mobile information services have become the mainstream direction of the current service industry. Today, as a bridge of information service, wireless communication is facing unprecedented opportunities, but it is also a more difficult challenge. Filter, multiplexer is the key component of isolating and extracting signal, and the spectrum resource is limited. In order to achieve the highest spectrum application efficiency, the division of wireless frequency band is more precise. In addition, the trend of electronics industry is miniaturization. Low cost and integration. Therefore, the development of micro high performance filters is particularly urgent for the current and future wireless communication development. Traditional cavity, coaxial and microstrip transmission line filters can not have the same performance. The current filter design needs to combine classical theory with industrial technology. With the development of LTCC low Temperature Co-fired Crystal Polymer and HTCC low Temperature Co-fired Ceramicics, especially ceramic material technology, integrated microwave is passive. The active circuit device has got a good development opportunity. The dual mode and multimode resonant level structure has the inherent miniaturization characteristics with its excellent electrical characteristics such as controllable fundamental mode and high order mode resonance frequency. It has been widely used in the design of engineering RF microwave filter. It has high efficiency, low cost and good performance. Miniaturization is the current electronic device. In the field of microwave filter, multi-mode resonance technology, capacitance equivalent technology and step impedance resonance technology are often used to realize miniaturization. The research trends of a large number of cutting-edge micro multimode filters are analyzed, and the applied methods and techniques are used to integrate the characteristics of double mode, multimode resonance and step impedance resonance. Five kinds of double structures are designed with the above technology and LTCC multilayer process. The multimode resonant filter, including narrow band filter, multistage high performance double mode filter and double pass band filter, verifies the flexible and controllable resonance characteristics of the multimode filter. The device volume is miniaturized, and the five filter volumes are mainly divided into two types, 4.8mm 脳 3.2mmx 1.5mm and 9.12mmx4.2mm 脳 1.5mm. these five filters can be widely used in mobile communication terminals, base stations and satellite communications. One of the miniature dual-mode high performance filters is a cooperative project with a national defense research institute. The simulation results fully meet the requirements of the target and are now in the later stage of processing.
