Development of a Ka-band Dual-mode Helix TWT

本文介绍了一种Ka波段双模螺旋线行波管的研制情况,其工作频率范围为32~38GHz,工作电压为9.5kV,低模工作比为70%,峰值输出功率为150~200W;高模工作比为10%,峰值输出功率为300~400W。该Ka波段双模螺旋线行波管具有工作电压低、快速启动、可无环控工作的特点,适用于航外有源诱饵弹等多种应用场景。

This paper introduces the development of a Ka-band dual-mode helix traveling wave tube(TWT).The TWT works from 32GHz to 38GHz with a voltage of 9.5kV.It outputs 150W peak power at the low mode with duty cycle of 70%and 300W peak power at the high mode with duty cycle of 10%.This TWT has the characteristics of low working voltage,fast warming-up and non-environmental control,which makes it suitable for various scenarios for example the off-board active decoy bombs.
