摘要: 本文從色散方程出發(fā),導(dǎo)出了迴旋磁控管的小信號增益表達(dá)式。估算了電子效率。用計算機進(jìn)行了計算,結(jié)果表明,在一定條件下,工作于6次諧波的8mm迴旋磁控管(f0=35GHz)的小信號增益可達(dá)2dB/cm,電子效率接近8％。這些結(jié)果為設(shè)計和改進(jìn)迴旋磁控管的工作特性提供了一定的理論依據(jù)。此外,為了提高效率,還提出了磁控管波導(dǎo)型迴旋佩尼管的設(shè)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. -
