Backward wave oscillation (BWO) and other parasitic oscillation are encountered in the process of manufacturing W-band TWT. In order to eliminate the oscillation, a kind of attenuation material is coated to the folded waveguide wall. This method presents a good performance to enable stable working of the TWT and increase the output power to 15W at the same drive level.
