Huawei will also officially release mobile phones supporting 5G networks in 2023. There are two paths in the 5G market: one is to put a 5G shell on Huawei's current 4G mobile phone, and the other is to redevelop the mobile phone with the so-called chip technology of the previous generation-redesign the 5G mobile phone chip and its architecture according to the chip technology available to Huawei at that time.

RF chips are more complicated. The RF front-end module (module) in mobile phone is very complicated, including many different modules, and different modules even have different suppliers. The four most important modules in RF front-end are filter, power amplifier, switch and low noise amplifier. In the field of RF front-end chips, the three RF giants Avago, Skyworks and Qorvo account for nearly 90% of the global share. These three companies are all American companies, so it is natural that Huawei cannot be provided with 5G-related RF modules according to the ban.
