Carry out the embodiment that the present invention will be described in detail below with reference to attached drawing, illustrated embodiment is served only for explaining the present invention,
It is not intended to limit the scope of the present invention.
A kind of double-layered central conductor coaxial high power ferrite circulator, as shown in Figure 1, 2, including the housing with inner cavity
1st, two ferrites of upper and lower in inner cavity are respectively arranged at and are respectively arranged at two permanent magnets of outer lower face surface on housing 1,
There is the port of three connection coaxial connectors 2, the port is connected with inner cavity, further includes two on the side wall of the housing 1
Center conductor and dieelctric sheet, what described two center conductors were distributed up and down is arranged between two ferrites, described two iron oxygen
It is filled between body formed with gap, the dieelctric sheet in gap.
In the present embodiment, the housing 1 with inner cavity is hexahedron structure, is made of metal, the thickness of housing 1 is h.Forever
Magnet A3 and permanent magnet B4 is respectively arranged at the outer surface top and outer surface lower part of housing 1, in the present embodiment, the iron oxygen
Body is disc-shaped, its a diameter of d1, thickness h1, it is to be understood that ferritic shape is not limited to disc-shaped, or
Cylinder or other shapes.The ferrite is provided with two, and ferrite A5 and ferrite B6, are arranged in inner cavity, iron up and down
The distance between oxysome A5 and ferrite B6 are h2, double-layered central conductor 7, this hair are provided between ferrite A5 and ferrite B6
It is bright that dieelctric sheet 8 is clipped in wherein it is possible to improve the power bearing ability of ferrite circulator using double-layered central conductor 7.Iron oxygen
Body and center conductor are in close contact, and also have gap after being filled between ferrite A5 and ferrite B6 by double-layered central conductor 7, described
Gap is filled with dieelctric sheet, and the dieelctric sheet can be made of microwave materials such as polytetrafluoroethylene (PTFE), boron nitride, ceramics, due to poly-
Tetrafluoroethene dielectric constant is small, and lossy microwave is small, temperature use scope is wide, soft texture, therefore dieelctric sheet in the present invention
Material preferably polytetrafluoroethylene.It is understood that in gap between ferrite after filled media piece 8, described two iron
Oxysome, two center conductors and dieelctric sheet is seamless is placed in inner cavity, can so ensure that ferrite will not after being stressed
Fragmentation, physical arrangement form will not be destroyed, thus function of going in ring keeps normal table, and high power will not be caused to strike sparks.
Each center conductor includes positioned at the interface portion at center and is arranged on three of interface portion periphery and is respectively directed to
The lead division of three ports, the center in the interface portion are overlapped with lumen centers, and three lead divisions are respectively from three ports
Housing 1 is pierced by with the coaxial connector 2 outside housing 1 to be connected.In the present embodiment, the interface portion is rounded, its thickness is h3,
Three lead divisions are Y-shaped to be welded together with interface portion, three lead divisions be pierced by housing 1 from corresponding port after with
Coaxial connector 2 outside housing 1 is connected.
In the present embodiment, the dieelctric sheet 8 is circle, is spliced by the sector structure that three apex angles are 120 °, institute
State dieelctric sheet 8 to be spliced using three parts, and integral structure cannot be used, dieelctric sheet 8 can be so put into bilayer
Between heart conductor 7.A diameter of d of the dieelctric sheet 82；Each sector structure is made of the different two parts of thickness, central part compared with
It is thin, thickness h4, between the interface portion of two center conductors, outer edge is thicker, thickness h5, positioned at two center conductors
Interface portion outside.Due to being filled up completely between ferrite sheet by dieelctric sheet 8, h2=h5。
In the present embodiment, the ferrite is disc structure, the ferritic diameter≤dieelctric sheet it is straight
Footpath, i.e. d1≤d2.Dieelctric sheet diameter is more than ferrite diameter, and the gap between levels ferrite can be filled up, filled out by dieelctric sheet
It is good to fill effect.
In the present embodiment, the ferritic center is overlapped with lumen centers, the ferrite upper surface or lower surface
Area>Interface portion upper surface or the area of lower surface.It can so make ferrite circulator impedance matching effect good, it is micro-
Ripple good electric property.
In the present embodiment, two ferrites, double-layered central conductor 7, dieelctric sheet 8 are according to ferrite A5, center conductor, Jie
Matter piece 8, center conductor, the order of ferrite B6 is seamless from top to bottom is placed in the inner cavity of housing 1, thus has following relation
Formula：H=2 × h1+h2；Or h=2 × h1+h3+h4.Between ferrite and the upper and lower surface of inner cavity, center conductor and ferrite and Jie
Connected between matter piece 8 using adhesive means.
When ferrite circulator works, permanent magnet A3, permanent magnet B4 magnetize ferrite sheet A, ferrite sheet B, after magnetization
Ferrite there is characteristics of non-reciprocity so that microwave energy is toward side rotation offset, when rotation angle and impedance matching are full at the same time
During sufficient condition, it is possible to realize function of going in ring.Due to the void area between levels ferrite, around center conductor interface
Dieelctric sheet 8 through being loaded is filled up completely, after ferrite is stressed, ferrite will not fragmentation, particle, physics will not be produced
Structural form will not be destroyed, thus function of going in ring keeps normal table.
The present invention circulator by the way that center conductor is designed to double-decker and loads PTFE medium piece, due to
The dieelctric sheet 8 that void area between levels ferrite, around the portion of center conductor interface has been loaded is filled up completely, and is being answered
The lower ferrite of power impact will not fragmentation, physical arrangement form will not be destroyed, improve circulator stability in use and can
By property, and under high power use environment, between ferrite filled media piece 8 can also avoid causing high power sparking from
And circulator and periphery relevant device is set to avoid being subject to fatal damage.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on, should all be included in the protection scope of the present invention.
