摘要： PURPOSE:To reduce the synthesis loss with a relatively simple constitution by constituting a cylindrical cavity constituting a synthesizer so that signal waves of the TM mode are generated and providing a filter, which stops signal waves of the TE11 mode, on the output line. CONSTITUTION:The height of a cylindrical cavity 1 constituting the synthesizer is made shorter than lambda/2. lambda is the wavelength of a free space for an operating frequency. If the diameter of a circular waveguide of the output line is so selected that the TM01 mode is propagated but the TE21 mode is intercepted, the TM mode is dominant in the electromagnetic field in the cylindrical cavity 1, and only the TE11 mode and the TM01 mode are propagated in the circular waveguide 3. The TE11 mode does not exist for the first intrinsic vector out of intrinsic vectors of a symmetrical circuit of N-number of terminals. When waves are oscillated with the second, the third,... the (N-1)th intrinsic vectors, the TE11 mode is propagated in the circular waveguide 3. A slit 4 is provided, and the TE11 mode is absorbed by a TM mode filter to which a resistance body is inserted according to conditions.
摘要翻译：目的：通过构成构成合成器的圆柱形空腔，以便产生TM模式的信号波并提供在输出线上停止TE11模式的信号波的滤波器，以相对简单的结构来减少合成损耗。构成：构成合成器的圆柱形空腔1的高度比λ/ 2短。 λ是工作频率的自由空间的波长。如果选择输出线的圆形波导管的直径使得TM01模式传播但是TE21模式被截取，则TM模式在圆柱形空腔1的电磁场中是主要的，只有TE11模式和TM01 在圆形波导3中传播模式。对于N个终端的对称电路的固有向量的第一本征向量，TE11模式不存在。当第二，第三，第（N-1）个本征矢量的波振荡时，TE11模式在圆形波导3中传播。提供一个狭缝4，TE11模式被TM 模式滤波器，根据条件插入电阻体。
