Substantive distinguishing features and obvious improvement that technical scheme of the present invention is outstanding are mainly reflected in:
The present invention has three ports of rectangular transform device and is the good waveguide junction type of the 3rd port match circulator/isolator, and signal gets into rectangle knot waveguide and triangle ferrite component through the rectangular waveguide mouth.Use the rectangular waveguide transmission signals, practiced thrift raw material, shorten installation time.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Fig. 1: structural representation of the present invention.
Embodiment
As shown in Figure 1, micro wave guide type circulator has three ports of rectangular transform device and is the good waveguide junction type of the 3rd port match circulator/isolator; Waveguide has the symmetry of 2 ports to the 3rd port, and two waveguide mouths are rectangles, and signal gets into rectangle knot waveguide and triangle ferrite component through the rectangular waveguide mouth; Ferrite component 5 is positioned on the converter; Ferrite component 5 is a symmetry shape for each port of waveguide junction, mono-hull 2 be respectively equipped with a groove that is used to deposit permanent magnet up and down, permanent magnet 1 and last permanent magnet 8 are installed; Form eternal magnetic field; Have gyromagnetic effect, mono-hull respectively has a rectangular waveguide transmission signals through inside, on the broadside plane of rectangle knot waveguide waveguide impedance transformer is installed; A leg-of-mutton ferrite component 5 is fixed on the rectangle knot waveguide step, and is positioned on the central axis of permanent magnet and following permanent magnet; Metal stick (metal electric magnetic conductor) the rectangle knot waveguide of packing into; Be used for the matched waveguide mouth; Link to each other with the ferritic corresponding sides of Y shape knot waveguide, the port width of Y shape knot waveguide is operated in 1/4 wavelength of waveguide frequency, and metal stick (metal electric magnetic conductor) is also isolated from the Y shape junction plane extension of Y shape knot waveguide each other; The both sides of metal stick are installed a microwave absorbing body member at least, are used to absorb the reflection power of this port (i.e. 3 ports); The waveguide of rectangle knot has the first circular metal piece 3 and the second circular metal piece 4; Its waveguide mouth has the one 90 ° of metal derby 6 and the 2 90 ° of metal derby 7; Coupling incoming signal and reflected signal, the 3rd port have the 3rd circular metal piece 9 and microwave absorbing body member 10, in order to regulate the coupling of microwave absorbing body member 10 and rectangular waveguide; And absorb and transmit microwave absorbing body member 10 rectangular block structures.
Wherein, Y shape knot is equipped with wave guide transformer through the rectangle transmission on the broadside plane of waveguide, and ferrite component 5 is bonded on the rectangle knot waveguide step through glue, is positioned on the central axis of waveguide impedance transformer and last permanent magnet and following permanent magnet; The port width of Y shape knot waveguide is in 1/4 wavelength of operating frequency.Three ports need metallic object to mate.Adopt mono-hull and the metal derby that is 90 ° of knuckles, the triangle ferrite need not combine just can realize the function of its needs with polytetrafluoroethylene.
3 port widths want much little than half-wavelength (λ/2) size of waveguide isolator operating frequency, realize the impedance matching function of waveguide transformer and microwave-absorbing body.Rectangular waveguide 3 port widths are less than half-wavelength "≤λ/2 " in the structure, and this structure comprises two thin metal sticks, is positioned near the waveguide opposite face of ferrite component, along above-mentioned waveguide, extends from rectangle knot place, and spacing is optional.Two identical microwave absorbing body components are installed in the both sides of metal stick.Two thin metal sticks are loaded into above-mentioned Y shape knot, link to each other with the corresponding sides of above-mentioned waveguiding structure, and rectangle knot port width is less than the half-wavelength " λ/2 " of operating frequency.The metal stick extends from the rectangle junction plane of waveguiding structure, and isolates each other.The 3rd port is adorned a progressive absorber, oblique line length " λ/2 " and be transformed to rectangular block then, be used to absorb the reflection power of this port (i.e. 3 ports).
