摘要

针对3.1- 5ghz超宽带接收系统，设计了工作频率为2.4 GHz的高选择性无源陷波滤波器。该滤波器旨在使IEEE 802.11 b/g和UWB标准在同一终端设备中共存。滤波器拓扑由两条路径组成:第一条路径包含全通函数，第二条路径包含带通函数。通过这种方式，信号在电路输入处被分割，并在其输出处组合形成陷波响应，该陷波响应在带通滤波器功能的中心频率处表现出高抑制。在罗杰斯4003多层基板上建立了实验原型，以显示该概念设计的优点。

Compact highly selective passive notch filter for 3.1–5 GHz UWB receiver system

This paper deals with the design of highly selective passive notch filter working at 2.4 GHz for 3.1-5 GHz UWB receiver system. The proposed filter aims to enable IEEE 802.11 b/g and UWB standard coexistence in the same terminal device. The filter topology is composed of two paths: the first path contains an all-pass function while the second path contains a band-pass one. By this way, the signal is divided at the circuit input and is combined at its output forming a notch response that exhibits a high rejection at the center frequency of the band-pass filter function. Experimental prototype implemented on Rogers4003 multilayer substrate is built in order to show the benefit of this concept design.
