Recently, National Intellectual Property Administration officially published the grant announcement for an invention patent independently developed by Shenzhen Microgate Technology Co., Ltd. The patent, titled 'A Method for Preparing Powder Material for RF Inductors' was officially granted on April 24, 2026.
Filed on February 17, 2023, the patent was developed by Microgate's R&D team, including Hu Geng, Geng Zhenwei, and Mei Tao. Its successful authorization after a rigorous examination process marks another step forward in Microgate Technology's innovation capabilities and intellectual property portfolio in core RF inductor materials.
Patent Highlights
This patent focuses on key material technology for RF inductors. It addresses a major industry challenge in high-frequency applications: achieving a better balance of high saturation, high permeability, and low loss in inductor materials.
The core process advantages include:
Classified particle-size screening and differentiated pretreatment of alloy-based raw powders and ferrite-based raw powders;
Insulation coating and annealing treatment for alloy powders, as well as pre-sintering, crushing, and cryogenic treatment for ferrite powders, helping improve insulation performance and magnetic stability;
Composite mixing, bonding, and granulation of the two powder systems to form RF-inductor powder materials with a uniform structure and strong overall performance;
Finished powder materials that deliver high saturation magnetic flux, high permeability, and low loss under RF conditions, while significantly improving insulation performance and inductor reliability.
This technology can be widely applied in high-end electronic component applications such as mobile communications, RF front-end modules, and high-frequency power supplies. It also provides critical material support for the continued development of Microgate's core products, including molded inductors and RF devices.
