摘　　要：该文根据谐波回旋速调管放大器的注.波互作用特点,分析了放大器稳定工作的条件:对Ka波段二次谐波三腔回旋速调管放大器的注-波互作用进行了模拟计算,对放大器的注.波互作用电路参数进行了优化设计。模拟计算结果表明,在电子注电压为70kV,电子注电流15A,工作磁场为0.685T时,在35GHz频率放大器可以获得超过250kW的输出功率,大于21dB的增益,23%的效率和约为120MHz的带宽。计算结果为实际工程设计提供了有益的参考。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.
