Abstract: Disclosed are a microwave ferrite material suitable for a 5G radio frequency device and a preparation method therefor. The preparation raw materials of the microwave ferrite material comprise a first microwave ferrite material and a second microwave ferrite material. In the microwave ferrite material provided by the present application, a double-component formula is introduced, proper ion substitution is employed, and ball milling and sintering processes are controlled, and therefore, the prepared microwave ferrite material has the characteristics of high saturation magnetic moment, high Curie temperature, narrow linewidth and low loss, and can be applied to industrial large-scale production of 5G radio frequency devices.
