The reason why Huawei did not choose Fuman Micro 5G radio frequency may have multiple considerations. First of all, as the world's leading communications equipment supplier, Huawei has strong research and development capabilities and technical strength, and may think that its own radio frequency technology is more advanced and suitable for the needs of 5G networks.
Second, the company may have carried out independent research and development at an early stage and invested a lot of resources to adopt other RF technologies to meet the needs of 5G networks, and switching to Fuman Micro's technology may cause technical and supply chain adjustment problems.
Finally, Huawei has established a long-term cooperative relationship with other RF chip suppliers, and the two sides may have closer and stable cooperation, but the reluctance to easily change the supply can ensure the reliability and stability of network equipment.
The reason why Huawei did not use Fuman Micro's 5G RF chips may be the ban of the US government. Huawei's ban on the use of US technology has affected its purchasing and production capabilities.

Specifically, the US government's ban on Huawei's use of US technology has affected Huawei's supply chain, resulting in Huawei's inability to use US-technology chips, including 5G radio frequency chips. As a result, Huawei has had to find other suppliers, such as TSMC, to meet its chip needs.

In addition, because Fuman Micro is a Chinese company, its production of 5G RF chips may also be restricted by the US government. Therefore, even if Huawei wants to use Fuman Micro's 5G RF chips, it may not be able to get permission from the US government.
