摘　　要：结合国内外微波铁氧体器件的发展趋势,综述了当今微波铁氧体材料领域的发展现状。对于石榴石型材料,低损耗、高功率和低成本等材料配方体系已相应建立。而对于尖晶石类材料,由于磁矩分布范围广,剩磁高等特点,在毫米波以及移相器件中得到广泛应用。对产品性能和产能规模等作了相应的阐述。重点指出开发微带用材料、低互调材料及铁氧体材料工程化的必要性和紧迫性,同时指出了研究思路和方法。Status and progress on microwave ferrite materials by combining the developing trend of microwave ferrite devices at home and abroad were summarized.In terms of garnet-based materials,new formulas have been developed with low loss,high power,and low cost materials.For spinel-based materials,they were widely applied in millimeter wave devices and phase shift devices due to the broad magnetization and high remanence.Also,product performance and production capability were clarified.It was emphasized on the importance and necessarity for the development of new microstrip materials and low intermodulation materials as well as industrialization of ferrites.Meanwhile,research ideas and methods were indicated.
