摘要

摘要: 行波管放大器(TWTA)廣泛應(yīng)用在雷達、通訊等領(lǐng)域。相位穩(wěn)定性影響傳輸信號質(zhì)量、目標參數(shù)檢測精度、電磁兼容性等指標。該文在定量分析電源調(diào)制器(EPC)電路參數(shù)對TWTA相位穩(wěn)定性影響的基礎(chǔ)上，提出提高TWTA相位穩(wěn)定性的EPC電路的幾種設(shè)計方案：選擇合理的供電電路，利用低壓儲能高頻高壓電源提高陰極電壓的穩(wěn)定性，利用調(diào)節(jié)控制脈沖幅度補償陰極電壓脈沖頂降造成的相位不穩(wěn)定性。該文成果為研制體積小、功率大、相位穩(wěn)定性高的TWTA提供了依據(jù)。

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.
