【Abstract】 A narrow band filter design method based on genetic arithmetic is provided in this paper. Theoretical analysis model is built up. A 50GHz filter is optimized according to the programme. Compared with the films system obtained by needle design, it has less bandpass loss, ripple coefficient and higher rectangle degree.更多还原
