摘要

高阶模谐波倍频陀螺仪可以使放大器获得高平均功率。改进的模式选择电路用于抑制非TE0n竞争模式，而壁损耗用于抑制TE0n竞争模式。预计g波段二次谐波倍增陀螺行波管在200 GHz时的峰值输出功率为56 kW，效率为11%，饱和增益为48 dB, 3db带宽为3.6 GHz。

Design of a G-band harmonic multiplying gyrotron traveling-wave amplifier with a mode-selective circuit

A high-order-mode harmonic multiplying gyro-TWA could allow the amplifier to achieve high average powers. An improved mode-selective circuit is employed for suppressing non-TE0n competing modes while wall losses are employed for suppressing TE0n competing modes. A G-band second harmonic multiplying gyro-TWT is predicted to yield a peak output power of 56 kW at 200 GHz with an efficiency of 11%, a saturated gain of 48 dB and a 3 dB bandwidth of 3.6 GHz.
