Meishen Technology Company
Microwave
dielectric ceramic as a new type of electronic materials, in the modern
communication is used as a resonator, filter, medium substrate, dielectric
antenna, dielectric guided wave circuit, etc., are widely used in many fields
of microwave technology, such as mobile phones, car phone, cordless telephone,
television, satellite receivers, satellite radio, radar, wireless remote
control, etc.
As 5G is officially put into
commercial use, 5G base stations will be covered in pieces nationwide, and
microwave dielectric ceramics have been widely used in the construction of 5G
base stations as filters.
Ceramic filter can not only ensure
high power output, but also have light weight, good temperature resistance
performance, long service life, miniaturization characteristics are also more
suitable for 5G base station highly integrated and miniaturized development
requirements.
High purity magnesium oxide has high
surface activity, high temperature characteristics and high purity. Therefore,
magnesium oxide is commonly used in ceramic filters to ensure good
conductivity, mechanical strength and high temperature resistance.
Magnesium oxide usually affects three
parameters of the filter:
1. The dielectric constant R
The size of the resonator is inversely
proportional to the square root of the dielectric constant of the dielectric
material. The larger the dielectric constant of the dielectric material, the
smaller the dielectric ceramic block required and the smaller the resonator
size.
2. Quality factor Q
The microwave dielectric material Q is
inversely proportional to the dielectric loss Tand.
The higher Q value is, the lower
insertion loss will be.
3. Resonance frequency temperature
coefficient F
The resonant frequency of microwave
dielectric material varies greatly with temperature, and the carrier signal of
the filter will drift at different temperatures.
The special magnesium oxide for
microwave dielectric ceramics of Hebei Meishen Technology Co., LTD has good
alkali resistance and electrical insulation.
High
thermal expansion coefficient and thermal conductivity, with good light
transmission and thermal conductivity.
Meishen is the world's leading producer of magnesium oxide, Magnesium oxide is
an oxide of magnesium, an ionic compound. It is a white solid at room
temperature. Magnesium oxide exists in the form of periclase in nature and is a
raw material for magnesium smelting. Magnesium oxide is white or light yellow
powder, odorless, tasteless, this product is insoluble in water and ethanol,
melting point 2852 ° C, boiling point 3600 ° C, magnesium oxide has high
refractory insulation properties. It can be converted into crystal by burning
at a temperature above 1000 ° C. If it rises above 1500 ° C, it will form a
burnt magnesia or sintered magnesia.
Magnesium oxide can be used in the
manufacture of metallurgy, smelting, advanced magnesia bricks, refractory
materials and moisturizing materials. It is also widely used in rubber, rubber
sheet, rubber products, pharmaceutical industry, food industry, plastic sheet
accelerator, glass fiber reinforced plastics and Surface coating of silicon
steel sheet, paper production, steel ball polishing, leather treatment,
insulation materials, grease, dyes, ceramics, desiccant, resin, flame
retardant, etc.
Hebei Meishen Chemical Technology
Group is the main magnesium oxide producer in the world. It is also the largest
magnesium salt producer in China and has won the ISO9002 quality system
certification. It also has GMP-Certification.
With
rich experience in the research, development, production, management and
operation of magnesium oxide products, Meishen Group has always attached great
importance to the research and development of new products and strict
requirements on product quality. Meishen has a high-level sales team. The
business covers more than 20 countries and regions around the world. It is
widely welcomed by new and old customers.
