Notes:
Numerical simulations of a W-band two-stage tapered, frequency multiplied gyrotron- traveling-wave-tube amplifier are reported. Unlike conventional harmonic gyrodevices, a drive signal at the fundamental harmonic frequency is injected in the first stage for beam modulation, and amplified output radiation is extracted from the third harmonic cyclotron resonance interaction. Numerical results show that broadband millimeter wave radiation is obtained with an efficiency of 10%–15%, a gain of ∼30 dB, and an instantaneous bandwidth of ∼10% at a center frequency of 95 GHz for Δvz/vz=2%.
