摘要: 本文从色散方程出发,导出了迴旋磁控管的小信号增益表达式。估算了电子效率。用计算机进行了计算,结果表明,在一定条件下,工作于6次谐波的8mm迴旋磁控管(f0=35GHz)的小信号增益可达2dB/cm,电子效率接近8％。这些结果为设计和改进迴旋磁控管的工作特性提供了一定的理论依据。此外,为了提高效率,还提出了磁控管波导型迴旋佩尼管的设想。

Abstract: Starting from the dispersion relationship of gyro magnetron, the expression of small-signal gain has been derived. The electronic efficiency is also estimated. The computing results show tha.t under defined conditions a gain per unit length of 2dB/cm and an electronic efficiency of nearly 8% a.t 35 GHz with 6th harmonie of the cyclotron frequency can be obtained. The computing results will be an useful information for design and improvement of gyro-magnetron. Moreover, the conceived gyro-peniotron with magnetron waveguide is proposed for efficiency enhancement. -
