Abstract. Results of calculation and measurements of intensity of modulation oscillations and spectrum of pulse-modulated output signal of amplifier on a basis of a new kind of microwave device – phase-stable travelling wave tube (TWT) are given. Advantages of these amplifiers over common ones in a spectrum of output signal are shown; questions of optimization of operating modes and characteristics of these devices are discussed.

Keywords: microwave amplifier, phase-stable TWT, modulation and out-of-band oscillations.
