Abstract

PURPOSE:To realize constitution which is miniature, but transmits and absorbs high electric power by fitting a plane type resistance body between one of strip line terminals and an earth conductor and by bringing a surface, which is not the film surface of the resistance body, into close contact with a soft magnetic material. CONSTITUTION:On a soft magnetic body 12, a ferrite core 6b is mounted via a shield plate 15b. On the core 6b, three center conductors 13a-13c are provided. A ferrite core 6a is mounted on them and covered with another shield plate 15a, on which a permanent magnet 3 is arranged. Further, a plane resistance body 21 is fitted to the magnetic body 12. At this time, a resistance film surface and the opposite surface to a terminal side are fitted to the magnetic body 12. Consequently, heat generated by the cores 6a and 6b and heat generated by the resistance body 21 owing to the absorption of reflected electric power are conducted to a heat sink through the magnetic body 12, so the transmission and absorption of high electric power are achieved even with small-sized constitution.
