Abstract

PURPOSE:To enable to branch about twice channels than conventional system at once, by reducing the size of filter to a half through the use of the cut-off guide tube inserting the dielectric resonator as band pass filter. CONSTITUTION:The electromagnetic waves having broad frequency components inputted from the input waveguide 1 are fed to the band pass filter having a plurality of different frequencies. Further, the waves are separated into the waves having narrow frequency components depending on the band pass filters 111-8. Then, they are outputted from the output waveguides 101-8 connected to the respective band pass filter 11. As the band pass filter 11, in place of conventional waveguide type resonators, dielectric resonator inserted to the cut-off waveguide having about a half size.
