As global 5G base stations surpass 18 million units, graphite sheets with thickness under 0.1mm are becoming indispensable components, thanks to their exceptional thermal conductivity (1000-2000 W/mK).


3 Key Application Areas:

1. Base Station Power Amplifiers

Some lab tests show graphite sheets can reduce GaN PA junction temperature by 15-20℃.


2. Milimeter Wave Antenna Arrays

At 28GHz frequency, graphite substrates decrease signal loss by 30% (Ericsson 2024 report).


3. Smartphone Thermal Modules

Some famous brands' latest foldable uses multi-layer graphite, achieving 8℃ lower temperature during 5G downloads.
