Abstract

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.
