Ceramics with high dielectric permittivity include microwave ceramics, high-frequency ceramics (HF ceramics) and ultrahigh-frequency ceramics (microwave ceramics), as well as plates made of ferroceramic materials.
Microwave ceramics is a class of materials with a dielectric constant E from 6 to 10000 and has a small tangent of the dielectric loss angle, high insulation resistance and electrical strength, high thermal conductivity, sufficient mechanical strength, as well as high temperature resistance. There are 3 main types of microwave ceramics:
Ferroceramic substrates - belong to the category of microwave ceramics and have a dielectric constant E from 600 to 15,000.
RF ceramics belong to the category of microwave ceramics, but are mainly used to create devices operating in the RF range. Ceramics have a dielectric constant E from 6 to 280.
Microwave ceramics belong to the category of microwave ceramics, but are mainly used to create devices operating in the microwave range and have a dielectric constant E from 7 to 140. At the same time, the substrates and such a material have extremely low dielectric losses.
In GN electronics, it is possible to vary the compositions of the materials offered to achieve the necessary characteristics, according to the customer's TOR and his individual needs.
Due to the large number of positions and possible variations of compositions, please request the necessary information and complete tables of characteristics from our engineers.
The tables are ranked: microwave ceramics (full description), HF ceramics, microwave ceramics.
