一种微带线射频带通滤波器的设计与研究
内容简介:针对特定混频器双端输出的边带信号的提取,设计一种工作在中心频率为750MHz的带通滤波器。介绍了变平衡为不平衡输出的实现原理,利用计算机辅助设计工具ADS进行设计微带线滤波器,给出微带线的PCB尺寸。仿真结果证明此带通滤波器参数符合应用要求。
Abstract:A microstrip band pass filter is designed. The filter worked at the center frequency of 750 MHz and used for the sideband signal extraction of particular radio frequency mixer. And then, the principle of changing doubleports balanced output into single port unbalanced is included. Based on computer aided design, the PCB size of mi- crostrip filter is determined by computer - aided design tools (ADS). The simulation results show the filter parame- ters to meet the application requirements.
