    • A magnetron includes an anode cylinder (1), a plurality of vanes (2) attached to the inside of the cylinder, a cylindrical metallic container (15), an output-side insulating tube (16), an antenna conductor (11), and a choke body (21). A hollow cylindrical metallic container (15) forms an airtight space at one end of the anode cylinder (1) and one end of a hollow output-side insulating tube (16) is airtightly connected to the container (15). An antenna conductor (11) electrically coupled with one of the vanes (2) extends through the cylindrical metallic container (15) and the output-side insulating tube (16). One end of a choke body (21) of a length of 1/4 wavelength of a harmonic to be suppressed is electrically coupled with the cylindrical metallic container (15), and its other end. The choke body is an annular groove type (21) or of a coaxial type (31).
    • 磁控管包括阳极筒(1),附接到气缸内部的多个叶片(2),圆柱形金属容器(15),输出侧绝缘管(16),天线导体(11), 和扼流体(21)。 中空圆柱形金属容器(15)在阳极筒(1)的一端形成气密空间,空心输出侧绝缘管(16)的一端与容器(15)气密连接。 与其中一个叶片(2)电连接的天线导体(11)延伸穿过圆柱形金属容器(15)和输出侧绝缘管(16)。 要抑制的谐波的1/4波长的扼流体(21)的一端与圆筒形金属容器(15)电连接,另一端电连接。 扼流体是环形槽型(21)或同轴型(31)。
