Parallel coupled band-pass filter is widely used in microwave circuits. For the purpose of improving band-pass performance and reducing design cycle, a kind of parallel coupled band -pass filter is designed by combining even and odd mode analysis and advanced design system( ADS) simulation. The centre frequency of the band-pass filter is 2. 51GHz and the relative bandwidth is 10%;all its parameters meet the design requirements. It’ s proved that the method has advantages of short design cycle and high reliability.
