本文分析了一个不寻常的偏转调制快波电子器件。它有若干极好的特性,电子注不聚束且垂直电路的功率流方向,电路可以是一个简单的基模矩形波导。放大器由电子枪、偏转腔、一个任选的电子注弯曲系统和一个输出互作用区组成。文章介绍了一个可以获得100％电子效率的理想化理论以及电子和电路效率超过90％的几个大信号计算,还讨论了这类放大器或频率倍增器的功率、增益和频率极限。因为输出电路损耗和偏转功率决定于电子控电压,而不是取决于电子注功率,为了有效地工作,电子控功率必须大于100千瓦、由于电子注尺寸与电路尺寸的比率的限制,器件最好工作在低于数千兆赫的频率。功率增益在10～25分贝之间变化。
This article analyzes an unusual deflection-modulated fast-wave electronic device. It has a number of excellent features, the electron beam is not focused and vertical power flow direction, the circuit can be a simple fundamental rectangular waveguide. The amplifier consists of an electron gun, deflection chamber, an optional electron beam bending system and an output interaction zone. The article presents an idealization theory that achieves 100% electron efficiency and several large-signal calculations with over 90% electronic and circuit efficiency. It also discusses the power, gain, and frequency limits for this type of amplifier or frequency multiplier. Because the output circuit loss and deflection power are dependent on the electronically controlled voltage and not on the electron injection power, the electronically controlled power must be greater than 100 kilowatts for effective operation and the device works best due to the electronically dimensioned to circuit size ratio constraints At frequencies below a few gigahertz. Power gain varies between 10 and 25 dB.
