Abstract
The utility model discloses a waveguide attenuator which comprises a primary wave and a secondary wave which are both with angles of 90 degrees. One end opening of the primary wave and one end opening of the secondary wave respectively serve as an input and an output. The primary wave is provided with a first load which is fixedly arranged on the other end opening of the primary wave through a first plug. The secondary wave is provided with a second load which is fixedly arranged on the other end opening of the secondary wave through a second plug. A straight line section of the first load of the primary wave is overlapped and connected with the straight line section of the second load of the secondary wave to form a coupling area. The straight lines in the coupling area of the primary wave and the secondary wave are provided with holes. A point end of the first load and a point end of the second load are respectively arranged on the inner wall of the primary wave and the inner wall of the secondary wave. The waveguide attenuator utilizes the multiple holes between the primary wave and the secondary wave to couple to realize great reduction. The output volume can be accurately controlled by controlling the numbers, positions, intervals of the holes and the thickness of the hole walls.
