摘要：
In this paper, an X-band air-cooled high efficiency traveling wave tube with coupled-cavity slow-wave structure and four-stage depressed collector was developed. The experimental results show that its average output power can reach more than 850 W and total efficiency is over 40% in the operating band (800 MHz). The X-band air-cooled high efficiency coupled-cavity traveling wave tube has met the requirements of airborne environment.
