    • PURPOSE: A radio frequency selection device for shielding an electromagnetic pulse is provided to select a wide frequency by using a matching filter for outputting a signal only in a desired frequency band to a protection room. CONSTITUTION: A matching filter passes different specific frequency bands. A rotator(50) is arranged in an enclosure to be rotated through the medium of a rotary shaft and a rotating member. A first insulating plate(60a) is arranged between the rotator and a first insulator(30a). A second insulating plate(60b) is arranged between the rotator and a second insulator(30b). The first insulating plate and the second insulating plate are rotated according to the rotation of the rotator.
    • 目的:提供一种用于屏蔽电磁脉冲的射频选择装置,通过使用匹配滤波器来选择宽频率,以将信号仅在期望的频带中输出到保护室。 配置:匹配滤波器通过不同的特定频段。 旋转器(50)布置在外壳中以通过旋转轴和旋转构件的介质旋转。 第一绝缘板(60a)设置在转子和第一绝缘体(30a)之间。 第二绝缘板(60b)设置在转子和第二绝缘体(30b)之间。 第一绝缘板和第二绝缘板根据转子的旋转而旋转。
