Why isn't Huawei p5 5G? What does it have to do with US sanctions?

The reason why Huawei P5 is not 5G is as follows. Although Huawei has Kirin chips supporting 5G, the international RF chip market is occupied by the United States and Japan, so it is difficult to localize it. Huawei has been purchasing RF chips from Sijiaxun in the United States before. After the first round of sanctions, Huawei began to purchase RF chips from NXP and Murata in Japan.

However, after the fourth round of sanctions, Huawei required all supply chain enterprises involved in American technology not to provide parts and components to Huawei's 5G communication equipment, including 5G RF chip combination and 5G baseband. It can be said that the US sanctions against Huawei's mobile phone business have formed a complete system.

In fact, Huawei Hisilicon, as a first-class chip design enterprise, began to conquer some components of RF components a long time ago, but Huawei still failed to conquer the core filter. Therefore, sanctions lead to no core filter. Therefore, it is impossible to produce 5G mobile phones
