资料介绍

设计了一款基于低温共烧陶瓷(LTCC)工艺的小型化边沿陡峭低通滤波器。该滤波器通过网络综合法设计,利用ADS和HFSS联合仿真进行优化,结合传输零点理论,在阻带设计两个位置可调的零点,可增加阻带抑制,并且通过合理设置各个元件的位置和外形,形成陡峭边带。实际加工出的滤波器性能与仿真结果吻合。滤波器截止频率500 MHz,通带插入损耗小于0.55 dB;在0.9 GHz、1.3 GHz处产生两个传输零点;825 MHz处衰达到23 dB,1.71 GHz处衰减达到31 dB,形成了陡峭的边带特性。该滤波器已在蜂窝通信中得到应用。

A miniaturized sideband steep low-pass filter based on low temperature co-fired ceramic(LTCC)technology is filter is designed by the network synthesis method,which is optimized by the co-simulation of ADS and order to increase the rejection of stop band,two adjustable transmission zeros are designed in the stopband to form the steep sidebands by reasonably setting the position and shape of each component in combination with the transmission zero point actual processing of the filter performance and simulation results are basically cutoff frequency is 500 MHz and the passband insertion loss is less than 0.55 two transmission zeros are located at 0.9 GHz and 1.3 GHz,respectively,so that the 23 dB attenuation at 825 MHz and the 31 dB attenuation at 1.71 GHz are s filter has been applied in cellular communication.
