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.
