摘要: |
设计了一种改进型的梳状线LTCC滤波器.在一般抽头式梳状线滤波器设计的基础上,结合电路仿真以及三维电磁场仿真,辅之以DOE(design of experiment)的设计方法,设计出一种高抑制、低插损多传输零点的滤波器.滤波器的实际实现采用在当今射频通信器件设计中流行的LTCC技术.该滤波器中心频率为2.45GHz,带宽150MHz,可以广泛运用于无绳电话、蓝牙模块,以及WLAN的射频电路中. |

() |
Abstract: |
A modified combline LTCC filter is designed.Based on the design of the tapped combline filter,combined with circuit simulation and 3-D EM simulation,the filter which can achieve a high rejection,low insertion loss and more transmission zeros is designed with the help of the method of DOE(Design of Experiment).The practical realization of this filter makes use of the LTCC technology that is popular in the design of RF devices.The filter has the central frequency of 2.45GHz and the bandwidth of 150MHz,and can be used widely in the RF design of wireless telephone,bluetooth module and WLAN(Wireless Local Area Network). |
