文档介绍：毕业论文-基于ADS的微波电路的设计
摘要
随着现代通信技术的不断发展, 射频/微波电路越来越得到重视和发展。微波技术越来越广泛的应用在了通信、雷达、环境检测和导航等众多领域;尤其在商业领域,其现代应用包括蜂窝电话、个人通信系统、无线局域网、电视与无线电广播、全球定位系统、射频识别标识、远距离电话通信和卫星通信等。
微波滤波器作为微波器件的一种也得到了大力的发展,其性能的优劣直接影响到整个微波系统性能的好坏。微带滤波器是微波滤波器的一种。本文着重讨论开路支节型宽带带阻滤波器的设计,描述了设计一个L波段带阻滤波器的过程。所设计的滤波器的技术指标为:中心频率2GHz; 通带带宽2GHz;阻带带宽600MHz;阻带衰减大于或等于30分贝。

Abstract
With the fast development munication technology, Microwave/RF circuit has attract more and more attention and also get many achievements. Microwave technology is widely used munication, radar, environment detective, Remote Sensing and many other fileds, especially mercial field such as cell phone, munication system, Wireless Local work (WLAN) , TV and radio broadcast, Global Positioning System (GPS), RF identification tagging,long-distance telephone and munications
and so on.
At the same time, as one of the important ponents, microwave filters also developed rapidly. The Microwave filter’s performance will directly influence the performance of microwave system. Microstrip filter is a kind of mircowave filters. The article focuses on designing broadband band-stop filters with open-circuited stubs and describes the process of designing a L wave band band-stop filter. It’s technology indexes are as follows: the midband frequency :2GHz; passband bandwidth: 2GHz; stopband bandwidth: 560MHz; Out-of-Band Rejection greater than or equal to 30dB; VSWR(Voltage Standing Wave Ratio) less than or equal to . Keywords: Microwave filters; microstrip; broadband band-stop filters with open-circuited stubs
