Aluminum & Aluminum Gadolinium Substituted Garnets Microwave Ferrite And Ceramic

Aluminum Gadolinium Substituted Garnets for below resonance applications with moderate temperature and power handling requirements, with useful switching properties.

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 ferrite band.

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:

A A. At the expense of high specific electrical resistivity (A A >106 OmA A.sm) ferrites are characterised by low dielectric losses at high frequencies tgA A'=10-2A A.10-4).

A A. Dielectric permittivity A AuAcA A (about 10-15)

A A. Thermal stability in a wide temperature range

A A. The high activity is being determined by the value of minimal bias which is essential for required nominal parameters providing.

Saturation magnetization, M s; 4 Ms (400-5000 G)

The width of resonance curve 2 is one of the main parameters characterising properties of ferrites applied in high-frequency band. The yttrium-iron monocrystals exhibit the minimal value 2H =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
