The parallel coupled microstrip band-pass filter is widely used in microwave circuit system. In order to improve the performance and reduce the design cycle, combined even and odd mode analysis with ADS emulation, a kind of parallel coupled microstrip band-pass filter is designed, which has a centre frequency of 2.5 GHz and the relative bandwidth of 10%. The last section of the paper optimizes the parameters of the filter and what＇s more, provides the physical cercuit diagram. The results show that the method has the feature of minor designing cycle and high reliability. The parameters satisfy the need of designing.
