PROBLEM TO BE SOLVED: To improve exhaust heat performance of both a filter and a hollow waveguide, while suppressing temperature rise of a waveguide filter.SOLUTION: An exhaust heat exchanger for waveguide filter includes a filter having an electric coupling hole, a first waveguide where a flange is arranged on one end face side of the filter, a second waveguide where a flange is arranged on the other end face side of the filter, one exhaust heat exchanger connected between the flange of the first waveguide and one end face of the filter, and arranged to surround the perimeter of the electric coupling hole circularly, and the other exhaust heat exchanger connected between the flange of the second waveguide and the other end face of the filter, and arranged to surround the perimeter of the electric coupling hole circularly. The flange of the first waveguide, one exhaust heat exchanger, the filter, the other exhaust heat exchanger, and the flange of the second waveguide are fastened together by means of fastening screws.SELECTED DRAWING: Figure 1 【課題】 ろ波器と中空導波管の両者の排熱性能を向上するとともに、導波管フィルタの温度上昇を抑制する。【解決手段】 電気結合穴を有したろ波器と、上記ろ波器の一方の端面側にフランジが配置された第１の導波管と、上記ろ波器の他方の端面側にフランジが配置された第２の導波管と、上記第１の導波管のフランジと上記ろ波器の一方の端面の間に接続され、上記電気結合穴の周囲を円形状に囲むように配置された一方の排熱器と、上記第２の導波管のフランジと上記ろ波器の他方の端面の間に接続され、上記電気結合穴の周囲を円形状に囲むように配置された他方の排熱器とを備え、上記第１の導波管のフランジ、一方の排熱器、ろ波器、他方の排熱器、第２の導波管のフランジを締結ねじにより共締めする。【選択図】 図１
