HiSilicon’s move towards an antenna to modem solution

Over the past three years, however, HiSilicon’s presence in the front-end components of Huawei mobile handsets has grown significantly which could signal a desire to provide an antenna to modem solution.
In 2017 TechInsights’ teardown activities revealed the presence of seven receive side front end components consisting of an LNA and RF switch module in five models of Huawei handsets. 2018 saw a small increase in the number of new components but the number of handsets that they were found in increased to 22.

The number of handsets that contained these components was 23. 2020 only saw 2 new components. A 5G NR FEM was found in the Huawei Nova 7 5G handset....
