“…Later, however, it was shown [10] that in higher power (about 30 W) nanosecond 3 cm range GDOs, the microwave oscillation phase is also stable at a fixed point on the leading edge of the voltage pulse if its rise time τ e ≈ 4.5 ns, which is much longer than the oscil lation period. Because of this, the phase stabilization in 3 cm range 30 W nanosecond GDOs is studied in greater detail experimentally and by numerical simu lation.…”

The "intrusion" of the phase of a Gunn diode nanosecond microwave oscillator by applying a modulating voltage pulse is numerically simulated. The dependences of the microwave oscillation phase on the spread of the pulse rise time and modulating pulse amplitude are revealed. The standard deviation of the phase lag time in a 3 cm range oscillator relative to a fixed level at the leading edge of the modulating phase is measured. Phase synchronization between two electrodynamically uncoupled oscillators that are simulta neously excited by a single modulator is studied experimentally.

“…In this way, crosstalk between the oscilla tors through the modulator was excluded. Measure ments were taken according to the technique described in [10,17]. The rise time of the pulse applied to the GD was equal to 6.4 ns.…”

The paper studies the influence of semiconductor structure on microwave oscillation phase stabilization in a nanosecond Gunn oscillator during the modulating voltage pulse rise time. The phase deviation depending on the pulse amplitude and rise time was determined by numerical simulation. The standard deviation of the microwave oscillation phase delay about a fixed level within the modulating pulse rise time and the standard deviation of the microwave oscillation phase difference in two electrodynamically decoupled oscillators were measured.
