Circular recess wave guide chamber stable oscillator

Abstract

Circular recess waveguide cavity steady oscillator is suitable for microwave, millimeter wave and submillimetre wave. In the circular recess waveguide cavity steady oscillator, an upper insulating bar and a lower insulating bar are fit on inside of front metal plate and rear metal plate to separate them separately, wedging shape matched dry loads are fit on inside of upper and lower insulating bars separately, a circular through-hole with diameter D along length direction of the plates at symmetrical center of end surface of two metal plates to form circular recess waveguid; a transistor base, a coaxial low pass filter and tuning screw are fit in space between two metal plates, the transistor base and coaxial low pass filter are in a same axis, the tuning screw and coaxial low pass filter are parallel, a high Q cylinder adjustable resonant cavity is fit on one end of circular recess waveguide, the axis of the cavity and the circular through hole are vertical.

Description

technical field [0001] The invention relates to a circular groove waveguide cavity-stabilized oscillator for microwave, millimeter wave and submillimeter wave, belonging to the technical field of oscillator manufacture. Background technique [0002] In the frequency range from microwave to submillimeter wave, there are generally two types of oscillators: one is composed of vacuum electronic devices and waveguides, and the other is composed of solid state devices and waveguides. The present invention belongs to the latter. [0003] Oscillators are the source of electromagnetic waves and are therefore one of the most important components in microwave, millimeter-wave, and submillimeter-wave technologies. Oscillators are the result of the combination of active devices and waveguides, and there is an oscillator suitable for each type of waveguide. Slot waveguide is a new type of waveguide, which has the advantages of large size, high power capacity, ...

Problems solved by technology

[0004] Although some people abroad have proposed rectangular slot waveguide oscillators and "V" shaped slot waveguide oscillators, these so-called "oscillators" are just a combination of rectangular waveguide oscillators plus rectangular waveguide-rectangular slot waveguide mode converters or rhombus The combination of waveguide oscillator plus rhombic waveguide—“V”-shaped groove waveguide mode converter, they are only rectangular waveguide oscillators or rhombic waveguide oscillators, and they are not real groove waveguide oscillators. So far, there is no one in the world. A real slot waveguide oscillator—that is, an oscillator composed of solid-state devices installed directly in the slot waveguide
