Microwave ferrite Garnets Yttrium Iron Garnets Al doped

Characteristics
In recent years due to success in the field of microwave electronics a lot of devices of dfferent 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:
1.At the expense of high specic etrial rsistvity (p >106 Om:sm) ferrites are characterised by low deletric lsses at high frequencies tgδε-10-2+104).
2.Dielectric permittivity뵪(about 10-15)
3.Thermal stability in a wide temperature range
4.The high activity is being determined by the value of minimal bias which is essential for required nominal parameters providing.
5.Saturation magnetization, M s; 4ÏMs (400-5000 G)
6.The width of resonance curve 20H is one of the main parameters characterising properties of frrites 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 plytalline frrites varies from 3...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 ±0,02 mm. In spite of standard variants of performance it is possible to produce ferrites in accoradance with sizes and customers drawings.
