A band pass filter combiner carrying a broadband signal with a central frequency comprises a power divider, a high pass band filter, a low pass band filter, and a power combiner. The distance from the signal input port of the power divider to each of signal input ports of the high pass band filter and the low pass band filter is equal to a quarter of the wavelength at the central frequency. The distance from each of signal output ports of the high pass band filter and the low pass band filter to the signal output port of the power combiner is also equal to a quarter of the wavelength at the central frequency.
