Description

Technical Field

[0001] The utility model relates to the technical field of circulator devices, and particularly relates to a high-power coaxial circulator structure. Background Art

[0002] A circulator is a multi-port device that transmits the incident wave entering any of its ports to the next port in the direction determined by the static bias magnetic field in sequence. A circulator, also called an isolator, is a non-reversible device with several ports. Its remarkable feature is the ability to unidirectionally transmit high-frequency signal energy. It is divided into micro-optical fiber and electronic circulators, and has good applications in isolators, duplexers, and reflection amplifiers. Since power is a very important reference factor in the design of a circulator, as the power increases, it is inevitable to choose large-size materials as the basis. When the material size increases, the carrier of the circulator material, that is, the outer shape size of the circulator cavity, also increases accordingly. Coupled with the limitation of the connector installation flange size, the thickness of the cavity will also be greater. Such a large volume will bring a lot of inconvenience to debugging. Content of the Utility Model

[0003] The purpose of the utility model is to provide a high-power coaxial circulator structure to solve the problem that the debugging of a high-power circulator is difficult due to the increase in size.

[0004] The utility model is realized through the following technical solutions:

[0005] A high-power coaxial circulator structure includes a circulator outer cavity, an embedded circulator, and an outward connection component. The embedded circulator is detachably installed in the circulator outer cavity. The outward connection component is arranged on the side wall of the circulator outer cavity, and one end of the outward connection component is electrically connected to the embedded circulator, and the other end of the outward connection component is electrically connected to an external device. To solve the above technical problems and achieve the corresponding technical effects, in the utility model, by detachably arranging the embedded circulator in the circulator outer cavity, the embedded circulator can be removed outside the circulator outer cavity, thus avoiding the influence of the circulator outer cavity and the outward connection component on the circulator debugging work.

[0008] Further: The installation part includes four fixed installation columns, and the arrangement positions of the four fixed installation columns are adapted to the positions of the installation holes on the embedded circulator.

[0009] Further: A threaded hole is provided at the top of the fixed mounting post. When the mounting hole on the embedded circulator is coaxially aligned with the threaded hole, a bolt is configured to fix the embedded circulator to the fixed mounting post.

[0010] Further: A fixed limiting plate is provided at the top of the fixed mounting post. The fixed limiting plate includes two vertical plates perpendicular to each other, and the two vertical plates are attached to two adjacent sides of the embedded circulator.

[0011] Further: It further includes a PCB circuit board, and the PCB circuit board is arranged between the embedded circulator and the external connection component;

[0012] Further: One end of the PCB circuit board is electrically connected to the microstrip line of the embedded circulator, and the other end of the PCB circuit board is electrically connected to the connector core of the external connection component.

[0016] Further: The outer cavity of the circulator includes a top end cover and a mounting cavity with an open top;

[0017] Further: The top end cover is detachably mounted on the mounting cavity.
