The rapid development of 5G in the mainland has made earth-shaking changes in our lives, and the closest changes to our lives are that 5G mobile phones are becoming more and more common.
However, as the leader in global 5G communications, Huawei holds the world's largest number of 5G patents. It accounts for 26% exclusively in the field of global communications. When major domestic mobile phone manufacturers have launched 5G smartphones, huawei's P50 series, nova 9 series and other high-end mobile phones launched by Huawei in 2021 cannot support 5G networks.
Obviously, 5G patented technology is far ahead in the world, but Huawei has been unable to release 5G mobile phones for a long time, and its mobile phone business has also fallen sharply. In fact, Huawei does not want to release 5G mobile phones, but it cannot be released. The main reason is still sanctioned by the United States, the chip supply is cut off, and the 5G RADIO frequency chip cannot be obtained.
If the lithography machine is the jewel in the crown of the semiconductor industry, and the LNG ship is the jewel in the crown of the shipbuilding industry, then the RF chip is the jewel in the crown of the analog chip. RF chip research and development is difficult, and the importance of mobile phones is self-evident. If there is no RF chip, the mobile phone can not receive the transmitted signal, and there is no difference between it and the brick.
Previously, the mainland's RF chip self-sufficiency rate was less than 2%, most of them relied on imports, and the technology of more high-end 5G RF chips was mastered by Western countries. Most of Huawei's 5G patents focus on communication technology, and RF chips almost all need to be imported.
When the United States did not impose chip sanctions on Huawei, Huawei generally imported RF chips from foreign manufacturers such as Qorvo, Epcos, and Murata. After being cut off, it can only get 4G RF chips from Zhuoshengwei and HiSilicon, and 5G RF chips, because domestic manufacturers have not been able to build them before, so Huawei can only helplessly shelve 5G mobile phones.
RF chip development and production is difficult, 5G RF chip production is even more difficult. In recent years, Huawei HiSilicon is also developing 5G RF chips, but because 5G RF chips have high technical barriers and patent barriers, and Huawei started relatively late, it still has not achieved much breakthrough.
But just recently, about the domestic 5G RF chip, there have been two milestones in a row.
In January, the domestic technology company Fumanwei officially announced that its self-developed 5G RF chip that can be used on smart phones has entered the mass production stage, and has been talking about cooperation with mobile phone manufacturers such as Transsion and Xiaomi.
On February 7, the secretary of the board of directors of Fumanwei made it clear on the investor interactive platform that the 5G RF chip independently developed and produced by the company is in mass production, not only that, the 5G RF chip of Fumanwei also has complete independent intellectual property rights, which is 100% independently developed.
In addition to Fumanwei, domestic chip manufacturers such as Kaiyuan Communications, Hanguo Tianxia, and Zhuoshengwei are also working hard to develop 5G RF chips for smart phones, and some have made great breakthroughs and are in trial production.
Although there is no Huawei in the current list of negotiated manufacturers of Fumanwei, we have no way of knowing whether the new models released by Huawei can use Fumanwei's 5G RF chips. However, the successful mass production of Fuman micro 5G RF chips has given other domestic enterprises a shot in the arm, and also let us see the possibility of domestic 5G RF chips breaking the monopoly and achieving independent substitution.
Another good news is that the first high-performance 5G RF transceiver chip in the mainland has been developed. Not long ago, Powercom officially launched the B20 chip, which is the first 100% self-developed high-performance 5G RF transceiver chip in mainland China. However, this chip is mainly used in private networks, mobile communication base stations and other fields, and cannot be used on mobile phones.
But the significance of the B20 chip is still significant. The early continent was also subject to people in this field, and the emergence of the B20 chip broke the gap in this field of the continent. If the final B20 chip can be successfully mass-produced, it can also greatly improve the supply capacity of the mainland in the field of 5G RF transceiver chips and achieve some domestic substitution.
Only self-sufficiency will not be "stuck in the neck" by people. After the two 5G RF chips are officially mass-produced and circulated, the mainland's excessive dependence on foreign RF chips will be effectively alleviated. Whether it is the construction of 5G base stations or the production of 5G mobile phones, a certain degree of chip self-sufficiency can be achieved.
Although the modification of shipping rules and the cut off of chip supply have caused a great blow to domestic enterprises, they have also made enterprises understand that they must have their own technology and industrial chain in order to be free from being controlled by others. The successful mass production of 5G RF chips also shows that we are not unable to do it. If you want to really rise, you must change the old idea of "building is better than buying" and firmly grasp the technology in your own hands!
