Description
The utility model is a kind of waveguide component that is used for the circular recess wave guide system, belongs to millimeter wave, the submillimeter wave technical field.
The transmission line of microwave region and light-wave band has many researchs, the millimeter wave between these two wave bands, and submillimeter wave is then developed laterly, especially short millimeter and submillimeter region.Short millimeter, the novel transmission line of submillimeter wave are all being sought to be suitable in countries in the world at present.In the prior art, short millimeter band also adopts the standard rectangular waveguide usually, but loss is very big; Submillimeter region often adopts beam waveguide, but physical dimension is too huge, and assembling is debugged also very difficult; The rectangular channel waveguide is because it is not easy to be connected and experience difficulties with the gyrotron that can export great power now, because the energy output device of gyrotron is a circular waveguide.Also do not have at present suitable can be used for short millimeter band, can be used for the wavemeter of submillimeter region again.
The purpose of this utility model is at the deficiencies in the prior art, and a kind of waveguide component that uses in the circular recess wave guide system of high-power millimeter wave, submillimeter wave---circular recess wave guide wavemeter that is suitable for transmitting is provided.
The utility model designs according to the circular recess wave guide transmission theory.It is by waveguide, input coupling aperture, output wave detector, and five parts of adjustable short piston and micrometer caliper are formed.It is characterized in that waveguide adopts circular recess wave guide, it is made of two metal plates that upper and lower insulation strip separates, have in the symcenter position of its end face one along the metal plate length direction manhole; The input coupling aperture is the circular hole that is fixed on the sheet metal center of circular recess wave guide one end; The output wave detector is that detection tube is put into the little dielectric material sleeve of high-frequency loss, teflon for example, pottery etc., put into metal cylinder again, and screw in the micrometer caliper screw mandrel termination coupling ring of detection tube, another termination delivery extension line by metal cylinder one end; The adjustable short piston is made of the shape sheet metal identical with empty graphic in the Waveguide end face.The sheet metal that constitutes the adjustable short piston can be formed by two, three or four, wherein the effect with three compositions is the best, material can be identical with waveguide material, thickness is quarter-wave, a gap is arranged, so that both do not contact between sheet metal and waveguide, be that quarter-wave insulating washer separates with thickness between the sheet metal, be fixed on then on the metal sleeve of output wave detector, in order to reach optimum efficiency, the plate face of the end face of metal sleeve and sheet metal is in a plane.The adjustable screw mircrometer gauge can make short-circuit plunger parallel moving in waveguide cavity, and the distance that moves can be read from micrometer caliper; The output current of detection tube can be read by the indicating instrument that links to each other with cable splice.For ease of the connection between waveguide component, the limit wall of waveguide input end is provided with connecting hole.
The utility model is based upon garden shape slot wave and leads on the basis, compared with prior art, have the low chromatic dispersion of low-loss, the waveguide cross-section size is big, the power capacity of transmission is big, is convenient to and outstanding advantages such as the gyrotron that produces short millimeter wave, submillimeter wave great power is connected.The little order of magnitude of the standard rectangular waveguide that its loss ratio is traditional; Cross sectional dimensions is bigger 6～8 times than the standard rectangular waveguide under the same frequency; So the power capacity of transmission is than the big manyfold of standard rectangular waveguide, the energy output device of gyrotron is a circular waveguide, so can change with circular recess wave guide easily.Circular recess wave guide is to transmit high-power short millimeter wave, can transmit the transmission system of the function admirable of high-power submillimeter wave again.The utility model is one of necessary element of forming the circular recess wave guide system.There is not wavemeter just can not know accurately that operation wavelength in the system, its effect are that wavemeter institute in existing other Wave guide system is irreplaceable.
