    Permanent SmCo magnets are a key component that applies the constant direct-current magnetic field to gyromagnetic ferrite, and directly affect working band, temperature stability and other parameters of circulator. Both ferrite and Samarium Cobalt magnets can serve as circulator magnets. Ferrite magnets may off-center and the performance of circulator become unstable, in the meanwhile, ferrite also cannot satisfy the miniaturization demand of 5G circulator. In this case, Sm2Co17 magnets are chosen as 5G circulator magnets even do not have the cost advantage. With the increasing construction of 5G base station, the demand for Sm2Co17 5G circulator magnets is experiencing explosive growth.

    SmCo magnet is mechanically weak, but magnetically very strong. They should be packed properly in order to help user to handle them safely. 10x1mm High Performance Disc SmCo Magnets for Instruments

    5G has attracted much attention due to its application prospect in vehicle networking and industrial IOT, while trade war between China and the United States also promotes the temperature. In fact, 5G has also caused an uproar owing to the mass production of 5G circulator magnets. Customized Permanent Disk 5G Circulator SmCo Magnets

    Circulator is a radio-frequency passive device in the mobile communication field that allows microwave or radio-frequency signal transmits in unidirectional ring. The one-way transmission characteristics are based on the gyromagnetic property of gyromagnetic ferrite. Gyromagnetic ferrite is a kind of ferrite material which polarization plane constantly rotates around transmission direction when the plane polarized electromagnetic wave travel through the ferrite in one particular direction under high frequency magnetic field. The one-way transmission characteristics are mainly served for mutual isolation between level and level or between level and system of radio-frequency equipment to ensure working independently, therefore, protect signal source and reduce frequency pulling, interference or unnecessary radiation which will efficiently improve circuit quality.
