PURPOSE:To minimize the number of parts, to facilitate the manufacture and to minimize the loss of a microwave by dividing a waveguide type demultiplexer symmetrically to the center along the same plane so that a main guidewave pipe and respective sub-guidewave pipes can be divided into two. CONSTITUTION:In a waveguide pipe type demultiplexer to provide a main waveguide pipe 31 composed of a hollow pipe and plural sub-waveguide pipes 34 and 35 protruded in the same plane direction from the side surface of each main waveguide pipe 31 to constitute band pass filters 32 and 33, the waveguide type demultiplexer is constructed to be divided symmetrically to the center line along the same plane so that the main waveguide pipe 31 and respective sub-waveguide pipes 34 and 35 can be divided into two. Thus, since the main waveguide pipe 31 and respective band pass filters 32 and 33 can be manufactured in a single body in the propagation direction of the microwave, the waveguide pipe type demultiplexer, which is small in the number of parts, facilitates the manufacture and small in the propagation loss, can be obtained. |
