Abstract
For a free-electron oscillator, problems of mode dynamics are studied for a case when the feedback has a wide, but finite band (the feedback coefficie nt depends on the frequency). It is shown that even a broadband frequency-d ispersive feedback can significantly affect both the electron-current thres hold of stability of the single-mode operation and the process of frequency tuning.
