摘要
随着移动通信的飞速发展和微波电路的高度集成化,微带线成为单片微波集成电路中信号传输的主要载体,本文从归一化低通滤波器出发,阐述了微带通滤波器的工作原理和设计过程。在此基础上借助ADS仿真软件设计微波滤波器,根据给定的滤波器技术指标,确定滤波器类型、结构和最佳级数。仿真结果表明此方法简单可行,满足工程设计要求。
With the rapid development of mobile communications and the high integration of microwave circuits. As one of the main transmission lines of monolithic microwave integrated circuit, Based on normalized low pass filter, the theory and design pro- cess of microstrip band pass filter are presented. An band-pass filter is given.According to the technical characteristics of filter, the type, structure and optimals tage number can be decided based on ADS. Simulated results are given and they are consistent with de- sign requiremen reasonable and efficacious
