Abstract(in English) A method of characteristic approximation for coupled resonators filter that maximaly flat attenuation and equal ripple group delay at passband is presented. They have the attenuation poles at real frequency to increase the attenuation of the stop band. And they have the attenuation poles at complex frequency for equal ripple group delay characteristic. Therefore, they become a good stop band characteristic compared with the Bessel filter and good group delay characteristic compared with the Chebyshev filter. The filter in this paper consists of parallel connected lowpass sectons. We expect that they are lower loss than that consist of series connected lowpass sectons because loss of elements do not increase.
