5 G millimeter wave AAU is a FR2 band macro station product with frequency range of 24.25 GHz-52.6 GHz. With the characteristics of super-large user capacity, super-large bandwidth, ultra-low delay, etc., it has excellent application value in some fields with extremely low delay requirements, and it can further release the potential of 5 G network. The 5 G mmWave AAU adopts wafer-level package shaping chip, high gain antenna unit, hybrid beam forming architecture and HDI technology to realize the highly integrated design of antenna RF integration. The application of integrated heat dissipation technology, such as microchannel siphon frame and externally embedded heat pipe, makes the product realize energy saving, consumption reduction and light and thin design. The products can be deployed in hot spots, large uplink capacity of enterprise private network and other scenarios.
