摘要：

Experiments on a unique, high-power, millimeter wave amplifier (a phase-coherent, harmonic-multiplying, inverted gyrotwystron) are reported. Superior stability resulted from two factors: (1) interaction between a relatively low order waveguide mode (TE22) and the beam wave at the fundamental cyclotron frequency in the input section, and (2) an internal mode filter in the highly overmoded (TE42), second harmonic output cavity. Bandwidth was 1.3% with peak gain of 33 dB around 31.8 GHz. The gain-bandwidth performance is a significant advance for gyrotron amplifiers operating in such high order modes.
