Introduction
Microwave ferrite magnets can generate constant magnetic field to control electric current so that microwave signal is amplified and information can be smoothly transmitted. Microwave magnets are widely used in magnetrons, cathode-ray tubes, isolators, circulator, etc. These electronic components are commonly applied in radars, satellite communications, remote control systems, electronic tracking, electronic countermeasures, etc.

Characteristics
In recent years due to success in the field of microwave electronics a lot of devices of different applications were produced. The prospects for future development of microwave systems with predetermined characteristics are mainly assigned by ferrite choise. However the choise of a material for a concrete application in microwave technique is a complicated task, as there are different requirements to different parts of microwave band. Among main characteristics of ferrites suitable for high frequencies are:

  • At the expense of high specific electrical resistivity (ρ >106 Ом·sm) ferrites are characterised by low dielectric losses at high frequencies tgδ=10-2÷10-4).
  • Dielectric permittivity ε (about 10-15)
  • Thermal stability in a wide temperature range
  • The high activity is being determined by the value of minimal bias which is essential for required nominal parameters providing.
  • Saturation magnetization, M s; 4πMs (400-5000 G)
  • The width of resonance curve 2ΔH is one of the main parameters characterising properties of ferrites applied in high-frequency band. The yttrium-iron monocrystals exhibit the minimal value 2ΔH =0.3-0.5 Oe. The width of resonanse curve of polycrystalline ferrites varies from 30…40 to 800-1000 Oe.

Configurations
Microwave ferrites and ceramics are being produced on the base of pressed powder sintered at high temperatures. After thermal sintering the items can be smoothed and/or polished. Company produces items with different forms. Dimensional allowance at mechanical treatment is ±0,025 mm. In spite of standard variants of performance it is possible to produce cores in accoradance with sizes and customers drawings.

Microwave Ferrite Materials
Materials on the base of yttrium iron garnets
HSMAG manufactures ferrites or ceramics on the base of compounds with garnet and spinel structures. Yttrium-iron garnets are applied for production of different high-frequency devices operating in low border of high-frequency band. The great interest to ferrites with garnet structure, particularly, to yttrium garnet is explained by narrow line of ferromagnetic resonance absorption. Such materials are also characterised by small magnetic losses; relatively high magnetization; high thermalstability.Often ions of Cobalt and Rare-earth ions (Dy), (Gd) are introduced to materilas structure in order to improve material characteristics for increasing of ferrite stability to Power.

Materials on the base od compunds with spinel structure
Ferrite materials on the base of Mg spinel are characterised by small values of coercive field strength and also by low magnetic and dielectric losses that allows to use them in fields far from resonance area. cocernintg devices operating nerby resonance area the great is interest is attracted to materials on the base of Ni spinel. Such ferrites are characterised by a wide range of magnetization and high thermal stability. Ferrites on the base of Li spinel can be used in discrete phase shifters. Small values of coercive field strength and thermal stability in operating temperature range and a wide range of saturation magnetization values are characteristic for such materials.
Advantages
We have our own quality control department which is constituted by an expert teams. Each microwave ferrite magnets must be exactly tested before sales to guarantee that they are of high quality and meet specific requirement of customers.
Designed for isolator and circulator sub-systems used in a wide range of frequencies in radio-communication systems, Ferrite materials are available in disc or triangular formats or as custom designs. The materials are based on HSMAG formulations, offering low deltaH (ΔH) values that are effective in reducing IMD.
By associating the ferrites with a dielectric material, it is possible to develop a wide choice of composites (FDA approved) for miniaturizing isolator/circulator designs.
Surface Treatment
In surface treatment, various protective claddings are applied on the surface of microwave magnets, includeing Ni-Cu-Ni, Zn, Au, Ag, Sn, Ti, TiN, Cr, etc. Besides, we can customize specific surface treatment for microwave ferromagnets according to requirements of customers.
Maintenance
DO NOT place microwave ferrite magnets in following environments to prevent them from rusting or reducing magnetic performance.
