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.
