Abstract :
Study on U-shaped microstrip meander-line slow-wave structure for a low voltage, wide bandwidth millimeter traveling-wave tube is presented. The electromagnetic characteristics and the sheet beam-wave interaction of this structure are carried out. The simulation results predicts that this millimeter-wave power amplifier is capable of delivering hundreds of watts output power in the frequency range of 29-38 GHz, and the peak power is about 200 watts with the correspond-ding gain of 33 dB at 35 GHz.
