Low-linewidth low-temperature sintering gyromagnetic ferrite phase shifter substrate and preparation method thereof
The invention discloses a low-linewidth low-temperature sintering gyromagnetic ferrite phase shifter substrate and a preparation method thereof, and belongs to the technical field of electronic materials. The material of the ferrite substrate is Ni < 0.18 > Cu < 0.2 > Zn < 0.62 > Bi < 0.02 > Fe < 1.98 > O < 4 >-nano LiZn spinel type gyromagnetic ferrite (hereinafter referred to as NCZB-nano LiZn for short) material. The invention provides a hot pressing sintering process for preparing the low-temperature sintered gyromagnetic ferrite phase shifter substrate with low line width. In the material formula, Bi < 3 + > ions are adopted to replace NiCuZn ferrite, so that the low-temperature sintering characteristic of the ferrite is realized. Besides, in order to further obtain a lower line width, nano LiZn ferrite is adopted for doping, the ferromagnetic resonance line width of NiCuZn ferrite is further optimized, grain growth is controlled in combination with a hot pressing sintering process, and finally the low-line-width low-temperature sintering gyromagnetic ferrite phase shifter substrate material is obtained. The wide application requirements of the microwave phase shifter in 5G/6G communication base stations and active phased array radars are met.
