Abstract

An analytical large-signal model of a 2-cavityemission modulated microwave amplifier (a `femitron?) with a field-emission cathode has been developed. Typical gain, efficiency and power-output results are presented for an S-band device that is currently under development. Gain predictions are in good agreement with earlier published results, but efficiency estimates are less optimistic than have been suggested elsewhere.

场发射微波放大器:再评价
建立了带场发射阴极的双腔发射调制微波放大器的大信号解析模型。给出了目前正在开发的s波段器件的典型增益、效率和功率输出结果。增益预测与早期公布的结果非常一致,但效率估计不如其他地方建议的那么乐观。
