| 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). |
