摘要在微波毫米波无线通信系统中，幅度均衡器是一种非常关键的器件，主要起着调谐补偿的作用，因此对于幅度均衡器的研究也是尤为重要。随着通讯技术的快速发展，集成密度增大，器件增多，这就需要幅度均衡器的体积愈小愈好，而LTCC技术可以容易的实现器件的小型化和高性能。基于LTCC技术的幅度均衡器是我们在这一领域中的首次尝试，具有非常大的可探索性，同时也充满了挑战。61667

首先，本文介绍了本课题的研究背景及意义，在国内外研究的现状，然后介绍了可以为均衡器技术带来变革的低温共烧陶瓷（LTCC）技术。其中详细介绍了一下几点：LTCC技术工艺流程，基板材料的介绍，该技术的 优点及存在的问题。

其次，本文将介绍幅度均衡器的分类和技术指标。涉及幅度均衡器电路参数的分析，

并研究了纯电抗的二段网络电抗频率特性和简单幅度均衡器的电路举例，最后叙述幅度均衡器的原理分析。

再次，基于LTCC技术设计了一款宽带的LTCC幅度均衡器。该幅度均衡器的频率范围为6~18GHz，与负斜率的均衡器不同，此款均衡器为正斜率。由于该幅度均衡器的频率较高，波长较长，电感电容值相对会比较小，其外形尺寸得以进一步缩小，仅为4.5mm*3.2mm*2.0mm。该款幅度均衡器不仅体积很小，而且性能较好，均可以满足技术指标要求。本文基于LTCC技术对一款L波段的幅度均衡器进行了研究与设计，在其均衡频带范围内，仿真结果呈现负斜率状态，频率范围为0.95~1.25GHz。此款幅度均衡器的设计采用的是由蛇形平面电感和双层平板电容构成的集总参数结构，使得均衡器的内部结构相对比较简单。我们采用LTCC技术进行了三维立体集成，使得器件体积较小，仅为4.8mm*4.2mm*2.0mm。

 Abstract In microwave and millimeter wave wireless communication system, the amplitude equalization is a very critical device and mainly plays a role of tuning compensation. Therefore the study of the amplitude equalizer is particularly important. With the rapid development of communication technology, the integration density and the device are both increasing, which require the volume of the amplitude equalizer as small as possible. And LTCC technology can easily achieve the miniaturization and high performance of the device. The amplitude equalizer based on LTCC technology is the first attempt in this area, it not only has a very large exploratory, but also is full of challenges.

First, this paper introduces the research background and significance of this topic, the status quo of research both at home and abroad, then introduces the can bring change for equalizer technology of low temperature co-firing ceramic (LTCC) technology. Which was introduced in detail the points: LTCC technology process, substrate material is introduced, the technical advantages and existing problems.

Secondly, this article introduces classification of amplitude equalizer and technical indicators. The analysis of the related to amplitude equalizer circuit parameters Reactance and studied pure reactance of the secondary network frequency characteristic and simple amplitude equalizer circuit as an example, the principle analysis of narrative amplitude equalizer.

Again, The amplitude equalizer for 6 ~ 18 GHZ frequency range, unlike negative slope of the equalizer, this equalizer is positive slope. Because the high frequency amplitude equalizer, a longer wavelength, inductance capacitance value relatively is small, its overall dimensions to further narrow, only 4.5 mm * 3.2 mm * 2.0 mm. The amplitude equalizer is not only small size, but with good performance and can meet the technical index requirements. this article is based on LTCC technology of a l-band amplitude equalizer has carried on the research and design, in its balance of frequency range, the simulation results show the negative slope state, the frequency range of 0.95 ~ 1.25 GHz. Cixin amplitude equalizer design USES is composed of coil plane inductance and double plate capacitance lumped parameter structure, makes the internal structure of equalizer is relatively simple. We using LTCC technology for 3 d integration, make the device volume is small, only 4.8 mm * 4.2 mm * 2.0 mm. And then designed a model based on LTCC technology of LTCC broadband amplitude equalizer.
