摘要:

阐述了EOC设备上双工滤波器的设计方法。滤波器由LC低通滤波器和LC高通滤波器组合而成,通过ADS2005仿真计算,研究了贴片电容和空心线圈电感,在FR-4板材上实现高性能滤波器的可行性。通过优化设计,提高了隔离度和带外抑制性能,对研制的滤波器电感线圈匝间距进行实验微调,产品匹配性良好,各项指标达到国家标准。

关键词: 滤波器, FR-4板材, 电感, 电容

Abstract:

This paper describes the implementation of a full duplex filter for the EOC device.This filter is composed of a LC low pass filter and a LC high pass filter.By simulation computing of ADS2005,this paper also researches the implemental availability of high performance filtering on FR-4 Board using the SMT capacitor and coil inductor.The result shows that the isolation level and Out of Band rejection performance are greatly enhanced by the use of the optimized design.By adjusting the space between the coil inductor of such filter,the EOC device can get better matching performance,and every metrics meet the national standard.

Key words: filter;FR-4 board;inductor;capacitor
