A W-band Traveling Wave Tube with ear-Folded Waveguide slow-wave structure
Millimeter-wave Traveling Wave Tubes(TWTs)have the characteristics of high power,broad band and high gain,and are widely used in modern military electronic equipment,such as radar,high-speed communication and electronic countermeasures,etc.In order to improve the coupling impedance of the Folded Waveguide(FWG)and the engineering applicability,a novel type of ear-FWG is proposed,which increases the coupling impedance in the working frequency band by more than 30% and reduces the loss by 10% compared with the conventional rectangular waveguide.When the ear-FWG W-band TWT operates at 21.9 kV and 210 mA,and the duty cycle is 5%,the output power in the 10.8 GHz bandwidth is higher than 192 W,the peak power reaches 278 W,the electron efficiency and gain reach 6.3% and 44.6 dB,respectively,and the TWT works stably.
