| 摘 要： | 采用低温陶瓷共烧( LTCC)技术设计了具有强阻带特性的低损耗全嵌入式带通滤波器(BPF)，提出了折叠边缘耦合带状线滤波器的小型化设计。为解决折叠耦合带状线的直角拐角引起的难以分析和设计难题，提出了神经网络结合遗传算法的优化设计方法。利用HFSS软件对滤波器接地通孔的位置和数目进行优化，改善了滤波器的传输特性。滤波器中心频率的插入损耗小于0.7 dB，反射损耗小于26 dB，滤波器尺寸2.3 mm×2.3 mm×0.41 mm，实现了小型化设计。

| Abstract: | A low-loss fully embedded bandpass filter(BPF) with enhanced stopband characteristics was designed by low-temperature co-fired ceramic(LTCC) technology.The folded parallel-coupled filters in edge-coupled strip line with miniaturization form were proposed.To resolve right corner analysis and design of folded coupled strip line,an opetimal design method was put forward by combining neural network with genetic algorithm.The location and number of grounded via were optimized by HFSS,to improve transmission char... |
