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.
Advanced Performance for Microwave ApplicationsHG Holmium Garnet Microwave Ferrite offers exceptional magnetic and thermal attributes, making it highly suitable for demanding RF and microwave device requirements. With precise line width (HWHM < 5 Oe) and impressive loss characteristics, this ferrite ensures efficient signal processing and minimal losses at high frequencies.
Versatile Customization OptionsCustomers can choose from a range of standard diameters (2 mm - 20 mm) or request custom sizes and shapes, such as discs or rings, to match their unique device needs. The ferrite can be finished in polished or sintered states, providing flexibility for various installation and interface requirements.
Reliable and Safe for Critical EnvironmentsEngineered with a high Curie temperature and broad operating range (-40C to +120C), this ferrite maintains stability in extreme conditions. High resistivity and RoHS compliance contribute to its safe integration in sensitive communications, radar, and power systems.
FAQ's of HG Holmium Garnet Microwave ferrite:
Q: How is HG Holmium Garnet Microwave Ferrite typically used in RF and microwave devices?
A: This ferrite serves as a core material in devices such as circulators, isolators, and phase shifters within RF and microwave communication and radar systems. Its magnetic properties help control the propagation and direction of microwave signals, enhancing device performance and signal integrity.
Q: What benefits does the high Curie temperature of ~370C provide?
A: A Curie temperature of approximately 370C allows the ferrite to retain its magnetic properties at elevated temperatures, ensuring reliable performance and extended operational life even in high-power or high-temperature environments.
Q: When should I select HG Holmium Garnet Microwave Ferrite over other ferrites?
A: Select this ferrite when you require exceptional thermal and frequency stability, very low loss, and high resistivity in your RF or microwave applications-particularly where performance at higher frequencies and temperatures is critical, such as in advanced radar or satellite communications.
Q: Where is this ferrite manufactured and distributed from?
A: HG Holmium Garnet Microwave Ferrite is manufactured, exported, supplied, and distributed by companies based in China, offering global availability through various distribution channels to meet industry requirements worldwide.
Q: What processes are involved in manufacturing and finishing these ferrite components?
A: Production involves sintering high-purity holmium garnet materials, followed by precision machining into specified shapes and sizes. The final pieces can be provided with a polished or standard sintered finish, depending on the application and customer preference.
Q: How does the high resistivity of >10^12 cm impact usage?
A: Such high resistivity allows the ferrite to minimize unwanted eddy current losses, maintaining signal clarity and efficiency even in high-frequency or high-voltage applications. This makes it suitable for use in high-performance microwave and RF environments.
Q: What packaging and compliance options are available?
