Abstract
The results of the development of a meander-line slow-wave system (SWS) with metal supports for a miniature high-power W-band traveling-wave tube (TWT) with two sheet electron beams are presented. Using a three-dimensional finite element software package, the electromagnetic parameters of the SWS were studied. A two-section model of a TWT amplifier with a sever to prevent self-excitation has been developed. Three-dimensional modeling of the beam–wave interaction has been carried out. It was found that with a total beam current of 200 mA in the linear mode, the gain exceeds 30 dB in the frequency band 95.4–97.75 GHz, and the output power in the saturation mode reaches 120 W. A technology for manufacturing SWSs based on laser micromachining of thin copper plates is proposed. Test samples of the SWS were fabricated and verified using optical and scanning electron microscopy.
