The report Huawei Technologies 5G NR Band n78: Model AAU5613 is part of the DesigN Analysis-Infrastructure (DNA-I) research series. The DNA-I series focuses on radio access network equipment teardown reports. These reports provide invaluable insight into the design philosophies and architectures for the major radio equipment OEMs as well as a full bill of materials (BOM) for major semiconductor integrated circuit (IC) and passive component products and suppliers.

The new report is on a Huawei Technologies 5G NR 64T64R massive MIMO active antenna unit (AAU), the AAU5613, which supports the n78 (3.5GHz) frequency band. The unit is targeted for the Chinese 5G NR market with an RF power output of 200 watts and employs Huawei Technologies' unique Cellular Liquid Cooler thermal technology.

“Everything associated with the design and manufacturing of the AAU by Huawei supports the fact it is the number one supplier of AAU shipments worldwide. The RF filter and antenna array subsystems use advanced technologies well beyond those of its competitors for similar generation AAU products,” says Lum.
