射频滤波器的设计与仿真 摘要 射频滤波器，主要用于电子设备、频率高工作更大的衰减高频电子设备产生的干扰信号。射频滤波器是最基本射频设备。能够由微带线组成，也能够由电阻,电容等组成。 由实践可知，很多射频系统中的元件不存在准确频率选择性，因此往往需要添加滤波器，用来极其准确地完成设定的选择特性，所以对射频滤波器的设计有重要的意义。在射频有源电路的各级之间都可以借助滤波器对射频信号进行隔离、选择或是重新组合。 在设计模拟电路时，需要对高频信号在特定频率或频段的频率重量做放大或衰减处理。这是十分重要的任务，因此本文将重点讨论如何设计和实现这个任务的射频电路——射频滤波器。关 键 词 ：射频，微波滤波器，微带线，workbench ,Advanced Design System； The design and simulation of radio frequency filters ABSTRACT Rf filter, mainly used in electronic devices, high frequency work greater interference signal attenuation of high frequency electronic device. Rf filter is the most basic radio frequency devices. Can consist of microstrip line, also can by resistance, capacitance, etc. The practice shows that a lot of rf components do not exist in the system accurate frequency selective, so often need to add the filter, used extremely accurately complete set of selected features, so the design of rf filter has an important significance. Between active rf circuit at all levels can use filter to segregate, choice or rearrange the rf signal. In analog circuit design, the need for high frequency signal at a particular frequency or frequency component in the spectrum for amplification or decay process. It is very important task, so this article will focus on how to design and implement the task of rf circuit, rf filter.
