Abstract
A parallel-coupled band-pass filter with 2 GHz center frequency and bandwidth of 260 MHz was presented for eliminating the interference of other signals to the mobile signal in subway lines. The implicit space mapping method was used in the design of the parallel-coupled band-pass filter and its optimization. The software HFSS and ADS were respectively applied in the establishment of the fine model and the coarse model of the filter. The insertion loss of the filter was less than 3 dB within 1. 85 GHz to 2. 15 GHz. The out-of-band rejection was greater than 20 dB when the stopband extended below 1. 75 GHz and above 2. 3 GHz. During the design of the filter, the implicit space mapping algorithm was verified to reduce the design costs.关键词
