ABSTRACT:
Undesired oscillations are suppressed in high-power, high-frequency, multe meanderline printed circuit traveling wave tubes. .pi. point frequency oscillations of various modes are attenuated by providing resistive coated longitudinal gaps in the ground plane conductor. The gaps permit lower radio frequency currents to propagate along the length of the line while blocking transverse currents of higher .pi. mode frequencies. The resistive coatings and spacing of the gaps control losses while permitting improved operation at the desired frequency. Increased beam current is produced at the output collector due to elimination of oscillations.
