摘要
提出了一种从圆波导 TE_(01)模到矩形波导 TE_(10)模的定向耦合器的设计方法。利用这种方法设计的用于高功率回旋速调管的-50dB 定向耦合器表明,改变矩形波导尺寸可以提高对圆波导 TE_(11)模的抑制度,而调整最后两个耦合孔的距离则可以优化方向性。
A method of designing a directional coupler from the TE_(01) mode in circu-lar waveguide to the fundamental mode in rectangular waveguide is presented in thispaper.The present method is used for designing a-50dB coupler for use inmeasurements of a very high power gyroklystron.The method of increasing the suppre-ssion of the TE_(11) circular mode by varying the rectangular waveguide size is reported.Bymodifying the distance between the last two coupling holes the coupler directivity canbe maximized.
