PIC Simulation of a Ka-Band Second Harmonic Gyroklystron Amplifier

  • 摘要: 該文根據(jù)諧波回旋速調(diào)管放大器的注.波互作用特點,分析了放大器穩(wěn)定工作的條件:對Ka波段二次諧波三腔回旋速調(diào)管放大器的注-波互作用進行了模擬計算,對放大器的注.波互作用電路參數(shù)進行了優(yōu)化設(shè)計。模擬計算結(jié)果表明,在電子注電壓為70kV,電子注電流15A,工作磁場為0.685T時,在35GHz頻率放大器可以獲得超過250kW的輸出功率,大于21dB的增益,23%的效率和約為120MHz的帶寬。計算結(jié)果為實際工程設(shè)計提供了有益的參考。
    Abstract: The conditions of the steady operation of the amplifiers are analyzed based on the characteristics of beam-wave interactions of harmonic gyroklystron amplifiers in this paper. The optimized design parameters of the circuit of the beam-wave interactions are obtained by simulation and calculation of the beam-wave interactions of a Ka-band, second harmonic, three cavities gyroklystron amplifier. The results show that this gyroklystron amplifier can produce an output peak power of over 250kW with more than 21dB gain and 23% maximum efficiency at 35GHz with a 70kV, 15A electron beam, and a 3dB bandwidth of about 120 MHz. This work is beneficial to the actual engineering design of the Ka-band second harmonic gyroklystron amplifier.
