Abstract

We present simulation results on wideband millimeter wave amplification on a coupled-cavity traveling-wave-tube driven by an ultra short impulse signal. The impulse signal of pulse width of 1 nsec modulated with a carrier frequency of 29.1 GHz is injected into the amplifier. The resulting output spectra were found to be wideband with a 2.4% fractional bandwidth at a center frequency of 29.1 GHz, where peak output power of 658 W remained same as that obtained at CW operation with a single drive frequency of 29.1 GHz.
