Problems solved by technology

However, during furnace welding, SMD circulators are prone to position drift. At present, most manufacturers use tooling fixture positioning and infrared scanning to ensure the reliability of SMD circulator welding.
[0003] Although the above method guarantees the reliability of SMD circulator welding to a certain extent, this method will not only increase the production cost but also affect the production efficiency

Abstract

The invention discloses a surface-mount-type microwave ferrite circulator, comprising a half-open cylindrical cavity with three through slots in the side wall and a stack part arranged in the cavity. The bottom of the cavity is provided with at least one positioning element. By arranging the positioning element, the circulator is enabled to be convenient to position in the subsequent welding process, and the welding precision is greatly improved. The low file design is adopted, the electromagnetic interference is reduced, and the improvement of the broadband performance is facilitated. A PIN needle is adopted for fixing a center conductor, so that the circulator is convenient in integrated installation. Iron-nickel alloy is used for manufacturing a temperature compensation sheet, so that the circulator is enabled to work stably and reliability at the limiting temperature. The cavity is plated with silver, so that the welding is enabled to be more reliable, and the conduction effect is better.

Description

technical field [0001] The invention relates to a circulator, in particular to a surface-mounted microwave ferrite circulator. Background technique [0002] Most of the existing surface-mounted microwave ferrite circulators (SMD circulators) are soldered to the PCB board by brushing tin. However, during furnace welding, SMD circulators are prone to position drift. At present, most manufacturers use tooling fixture positioning and infrared scanning to ensure the reliability of SMD circulator welding. [0003] Although the above method ensures the reliability of SMD circulator welding to a certain extent, this method will not only increase the production cost but also affect the production efficiency. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a surface-mounted microwave ferrite circulator with convenient positioning and high welding precision. [0005] In order to solve the above technical problems, the tec...
