本文陈述一种双级M型放大器件,它的互作用空间高度呈阶梯形变化,阳极直流电压是隔离的。在这种放大管中,克服了效率与放大系数之间的矛盾。此外,本文还探讨了对放大管的修正,提出一种新的元件,即“有源”磁控电子枪,它起着电子注入器和高频调制器的作用。当前,大多数M型放大器件的放大系数此较低,仅为10～20分贝。研制一种既有高效率 This article describes a two-stage M-type amplifier device, its interaction space height ladder-like changes, the anode DC voltage is isolated. In this amplifier, to overcome the contradiction between efficiency and amplification factor. In addition, this article also discusses the correction of the amplifier tube, and proposes a new element, the “active” magnetron gun, which functions as an electron injector and a high-frequency modulator. Currently, the amplification factor for most M-type amplification devices is low, only 10-20 dB. Develop a high efficiency
