PROBLEM TO BE SOLVED: To improve power resistance characteristics of a whole resistance terminator by improving heat dissipation characteristics of a resistance element.SOLUTION: A resistance circuit is constituted by connecting an impedance transformer composed of a cascade connection of transmission lines 3, 3a and 3b and resistance elements 2a and 2b having a relatively small resistance value to resistance elements (B, C) having a resistance value Zo, a basic resistance circuit having input impedance Zo is prepared by bundling two resistance circuits, and further the resistance terminator is constituted by substituting a part of the resistance elements (B, C), which has the resistance value Zo that the basic resistance circuit includes, with a resistance circuit having the same constitution as the basic resistance circuit itself. |
