Product Description

Microwave Ferrite Technology, Inc.


Microwave Ferrite Technology, Inc. is a leading manufacturer of microwave ferrite materials for the wireless industry in China. We provide a wide range of products, from high-volume garnets for wireless infrastructure to specialized materials for radar applications.


Applications

Our materials are designed for:

  • Above-resonance devices (100 MHz to ~3 GHz)
  • Below-resonance devices (1 GHz to 40 GHz or higher)
  • High-power and phase-shifting applications


Our Ferrites & Magnetic Materials

We offer a diverse range of advanced ferrite and magnetic materials, including:

  • Narrow Linewidth Ferrites: Optimized for high-frequency applications with minimal resonance absorption.
  • Aluminum & Aluminum-Gadolinium Substituted Garnets: Enhanced thermal stability for specialized microwave systems.
  • Gadolinium-Substituted Garnets: Superior magnetic properties for advanced signal processing.
  • Cobalt & Holmium-Doped Garnets: Performance-boosting materials for high-power microwave applications.
  • Magnesium Spinels: Low-loss materials ideal for reduced magnetic interference in devices.
  • Nickel Spinels: High magnetization and excellent thermal stability.
  • Lithium Spinels: Ideal for discrete phase shifters with wide saturation magnetization properties.
  • Permanent Magnets: Including ferrite and rare-earth magnets for industrial and scientific applications.


Key Characteristics

Our ferrites are engineered for high-frequency performance:

  1. High specific electrical resistivity (ρ > 10⁶ Ω·cm), ensuring low dielectric losses (tgδε: 10⁻² to 10⁴).
  2. Dielectric permittivity (ε’ ≈ 10–15).
  3. Excellent thermal stability across a wide temperature range.
  4. High activity with minimal bias for optimal nominal parameters.
  5. Saturation magnetization (4πMs: 400–5000 G).
  6. Narrow resonance linewidth (2ΔH: 0.3–0.5 Oe for yttrium-iron monocrystals; 3–1000 Oe for polycrystalline ferrites).


Configurations

Our microwave ferrites and ceramics are available in various shapes and compositions, with precision manufacturing to meet custom requirements.
