Abstract

The invention relates to electronics. The purpose of the invention is to reduce power unevenness while expanding the range of operating frequencies. . The generator contains segments 1 and 2 p 1 of a mongular waveguide, diode 3, conductors 4 and 8, a low-pass filter 5, a gyromagnetic resonator (HMR) 6 and a moving short-circuiter (PCZ) 7. When voltage is applied to conductor 8, diode 3 excites the main oscillations and their harmonics in the conductor 4. Since Since segment 1 is made beyond the fundamental dL, then the second harmonic oscillates through it. The implementation of the introduced segment 2 beyond the second harmonic and the placement of the diode 3, filter 5 and GMP 6, electromagnetically connected with conductor 4, on the end face of the SCR 7 ensures that the conditions for generating fundamental oscillations are not constant during frequency tuning of the GMR 6, which is used as a frequency tuning element. This causes a decrease in power unevenness while expanding the range of operating frequencies. 1 il. Q

Description

The invention relates to electronics and can be used for the excitation of microwave oscillations.

The purpose of the invention is to reduce power irregularity while expanding the range of operating frequencies.

The drawing shows a microwave generator, a general view.

The microwave generator contains segment 1 and the additionally inserted segment 2 of a rectangular waveguide, diode 3, conductor 4, filter 5 lower frequencies, gyromagnetic resonator 6, used as a frequency tuning element, movable short-circuit switch 7, conductor 8.

The microwave generator works as follows.

I When applying power to the conductor 8, diode 3 excites the main oscillations and their harmonics in conductor 4. The frequency of these oscillations is determined by the frequency of the gyromagnetic resonator 6. The filter 5 prevents penetration of the excited oscillations into conductor 8. Since segment 1 is made beyond the fundamental oscillations, the second harmonic oscillation propagates through it. The addition of the introduced length 2 beyond the second harmonic and the placement of the diode 3, filter 5 and gyromagnetic resonator 6, which is electromagnetically coupled to conductor 4, is movable on the end surface V.Shkalikov editor M.Tobtin Tekhred L.Oleinik.
