摘　　要：介绍一种在理论计算的基础上,采用ADS软件对射频滤波器进行优化及仿真的方法,重点阐述射频滤波器设计过程中的优化设计、器件仿真以及矩量法分析等相关内容。射频滤波器的测试结果表明其通带内波纹小于3dB,带内输入输出端口反射系数小于-20 dB,阻带衰减大于40 dB,相比于传统设计方法,此方法具有可行性和有效性。A method based on the theoretical calculation to optimize and simulate RF filter by ADS software is introduced. The optimization design, device simulation, moment method analysis and related content in the process of RF filter design is elaborated emphatically. The test results of RF filter show that the ripple within its passband is less than 3 dB, the reflection co- efficient of in-band I/O ports is less than -20 dB and stopband attenuation is greater than 40 dB. This method has higher feasibil-ity and effectiveness, compared with the traditional design method.
