摘要

摘要: 行波管放大器(TWTA)广泛应用在雷达、通讯等领域。相位稳定性影响传输信号质量、目标参数检测精度、电磁兼容性等指标。该文在定量分析电源调制器(EPC)电路参数对TWTA相位稳定性影响的基础上，提出提高TWTA相位稳定性的EPC电路的几种设计方案：选择合理的供电电路，利用低压储能高频高压电源提高阴极电压的稳定性，利用调节控制脉冲幅度补偿阴极电压脉冲顶降造成的相位不稳定性。该文成果为研制体积小、功率大、相位稳定性高的TWTA提供了依据。

Abstract: Traveling Wave Tube Amplifier (TWTA) is used extensively in the fields of radars and communication. And its phase stability could exert influence upon the quality of transmission signals, the detection accuracy of target parameters and the electromagnetic compatibility. This paper quantitatively analyses the effects of Electric Power Conductor (EPC)s circuit parameters upon the phase stability of TWTA, and proposes further advanced three designing schemes on the EPC to improve the phase stability of TWTA, i.e. selecting a reasonable power supply circuit; adopting low-voltage-charging, high-frequency, high-voltage source to raise the stability of high-cathode voltage; compensating the phase instability from the cathode voltage pulse top fall effect through the adjusting of the amplitude of control pulse. This paper provides theoretical basis for the researching of TWTAs with compact size, high power, and high phase stability.
