Application Scenario: Power amplifier units in 5G base station AAUs.
Challenges: High power density generates significant heat, requiring efficient heat dissipation. Outdoor environments require materials that are resistant to UV aging and temperature cycling.
Solution: High thermal conductivity (≥1.5 W/m·K), UV-stable silicone gel is used for potting.
Value: While efficient thermal conductivity ensures power amplifier performance, the silicone gel's weather resistance ensures long-term reliability in outdoor operation, reducing maintenance requirements.
