| 摘 要： | 介绍了一种通带为0-1.2 GHz的LTCC多层低通滤波器快速设计方法。利用滤波器设计软件,通过选择相应的参数,可以快速地设计出低通滤波器电路图,再将原型电路在三维电磁场仿真软件HFSS中建立滤波器模型。根据厂商提供的电容、电感等元器件模型库,根据模型库中的电容、电感值估算本次设计所需的元件大小,在HFSS中可以快速的建立模型,仿真结果可以很快的满足指标要求。最后采用标准LTCC工艺实现出尺寸为3.2 mm×1.6 mm×1.0 mm的低通滤波器。运用该方法可以帮助工程师快速地设计LTCC滤波器,有很强的实用性和便利性。

| Abstract: | A rapid design method of LTCC multilayer lowpass filter working at DC~1.2 GHz is introduced.By using the filter design software and choosing proper parameters,the circuit diagram of lowpass filter can be design quickly.The lowpass filter model is built in the HFSS through an analytical method.Based on the element model storeroom offered by the manufacturer,each component of the circuit can be extracted.The 3.2 mm×1.6 mm×1.0 mm lowpass filter was achieved by means of standard LTCC technology.This method can help engineers to design LTCC filter quickly.It has strong practicality and convenience. |
