F4BTMS High Frequency Material
The F4BTMS series is an upgraded version of the F4BTM series. Building upon its foundation, significant technological advancements have been made in material formulation and manufacturing processes. The material now incorporates a large amount of ceramics and utilizes ultra-thin and ultra-fine fiberglass cloth reinforcement. These enhancements have greatly improved the material's performance, resulting in a wider range of dielectric constants. It is a high-reliability material suitable for aerospace applications, capable of replacing similar foreign products.
By incorporating a small amount of ultra-thin and ultra-fine fiberglass cloth reinforcement, along with a significant and uniform mixture of special nanoceramics and polytetrafluoroethylene resin, the fiberglass effect during the propagation of electromagnetic waves is minimized, reducing dielectric loss and enhancing dimensional stability. The material exhibits reduced anisotropy in the X/Y/Z directions, allowing for higher frequency usage, increased electrical strength, and improved thermal conductivity. The material also possesses excellent low coefficient of thermal expansion and stable dielectric temperature characteristics.
The F4BTMS series comes standard with RTF low roughness copper foil, which not only reduces conductor loss but also provides excellent peel strength. It can be paired with copper-based or aluminum-based options.
Typical Applications
Aerospace equipment, space, cabin equipment
Microwave, Radio frequency
Radar, military radar
Feed network
Phase-sensitive antenna, phased array antenna
Satellite communications.
