The present application provides a circulator described below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the circulator includes:
the structure comprises a cavity 100, wherein an opening is formed in the upper end of the cavity 100, and at least three first grooves 110 communicated with the opening are formed in the side surface of the cavity 100;
the gyromagnetic ceramic substrate group 200 is arranged in the cavity 100; the gyromagnetic ceramic substrate set 200 comprises a central conductor 220 and two gyromagnetic ceramic substrates 210, wherein the central conductor 220 is clamped between the two gyromagnetic ceramic substrates 210, the central conductor 220 is provided with a plurality of pins 221 matched with the first grooves 110, and each pin 221 penetrates through the corresponding first groove 110;
the grounding sheet 300 is stacked on the gyromagnetic ceramic substrate set 200 and is positioned in the cavity 100;
the permanent magnet 400 is stacked on the grounding plate 300, and the permanent magnet 400 is located in the cavity 100.
The gyromagnetic ceramic substrate 210 is a substrate made of ceramic in which a gyromagnetic material is added to a high-dielectric material. At this time, under the condition of the same dielectric property, the volume of the gyromagnetic ceramic substrate 210 is smaller than that of a substrate made of a gyromagnetic material; meanwhile, compared with the mode of stacking gyromagnetic substrates and ceramics, the dielectric property is better, and therefore, under the condition of the same dielectric property, the volume of the gyromagnetic ceramic substrate 210 is smaller, so that the volumes of the cavity 100, the grounding plate 300 and the permanent magnet 400 can be reduced, and a circulator with a smaller volume is realized.
It should be noted that one of the pins 221 of the central conductor 220 is provided as an input pin 221 for inputting signals, and the other two pins 221 are output pins 221 for outputting signals. In some embodiments, as shown in fig. 1, the pins 221 are disposed through the first recess 110, and at this time, the pins 221 may be plugged into an external circuit to form a circulator of a Drop in mounting structure. In other embodiments, as shown in fig. 3, after the pin 221 passes through the first groove 110, one end of the pin 221 is bent toward the bottom of the cavity 100 and then bent, so as to form a surface facing parallel to the bottom of the cavity 100. At this time, the circulator can be connected with an external circuit in a surface-mounted manner.
When the circulator is matched with the quasi-lumped circuit, a product provided with the circulator and the quasi-lumped circuit can be more miniaturized.
Therefore, a closed magnetic circuit is formed by the cavity 100 and the permanent magnet 400, and a bias magnetic field is provided to the gyromagnetic ceramic substrate 210. The bias field at this time changes the conduction direction of the input signal of the center conductor 220. And because the gyromagnetic ceramic substrate 210 has a high dielectric coefficient, in a low-field working mode, compared with a traditional low-field circulator adopting a single gyromagnetic substrate mode, the gyromagnetic ceramic substrate 210 and the permanent magnet 400 can be designed to be smaller and meet the requirement of a bias magnetic field at the same time, and therefore the circulator is smaller in size.
It is understood that the permanent magnet 400, the grounding plate 300 and the gyromagnetic ceramic substrate set 200 are riveted and fixed in the cavity 100. Through riveting and fixing, the fixation of external parts is reduced, so that the device can adapt to the design of smaller volume.
It can be understood that one end of each pin 221 is bent toward the bottom of the cavity 100 through the corresponding first groove 110.
It should be noted that, as shown in fig. 3, one end of each lead 221 is bent twice toward the bottom of the cavity 100, so as to form a first bending surface 222 and a second bending surface 223 that are perpendicular to each other, the first bending surface 222 is spaced from the outer surface of the cavity 100, and the second bending surface 223 is on the same horizontal plane with the bottom of the cavity 100, so that the circulator can be mounted in a surface mounting manner.

It should be understood that, since the circulator is provided in a smaller size, the height of the circulator can be adjusted by the first protrusion 510 of the cover plate 500 when the circulator is installed in the drop, thereby improving the convenience of use of the miniaturized circulator.
It is understood that the circulator further includes a spacer 600, and the spacer 600 is disposed between the cover plate 500 and the permanent magnet 400.
It is understood that the surfaces of the ground strip 300, the central conductor 220, and the permanent magnet 400 are provided with gold or silver plating layers.
It is understood that the thickness of the gyromagnetic ceramic substrate 210 is set to 0.8mm, the thickness of the center conductor 220 and the thickness of the ground plate 300 are set to 0.1mm, and the thickness of the permanent magnet 400 is set to 0.5 mm.
It is understood that, as shown in fig. 2, one side of the gasket 600 and the ground plate 300 is provided with a second protrusion 710 matching with the first groove 110.
