Nickel (Ni) Spinels - Microwave Ferrite, Ni Ferrite Material Series Microwave Ferrite and Ceramic

Nickel Spinels Microwave Ferrite for below resonance applications requiring 4PiMs in the range 500 to 5000 Gauss, with useful power handling capability. Some have useful switching properties.

CHIYUE is a manufacturer of microwave ferrite materials for the wireless industry in China. Our products range from high volume garnets for wireless infrastucture to specialized

materials for radar applications. Applications require materials which work best in above resonance devices from 100 MHz to around 3 GHz, and another range of materials which suit devices working below resonance from about 1 GHz to 40 GHz or more.

Another set of materials are available for high power applications.

Some have suitable switching properties for devices based on below resonance phase shifting.

Introduction

Characteristics:

At the expense of high specific electrical resistivity (ρ >106 Om·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.
