Many related core technologies are in the hands of foreign suppliers, but domestic products have been developing and progressing. Finally, the good news came. Domestic enterprises released key 5G RF transceiver chips to achieve a breakthrough from 0 to 1. What kind of chip product is this? Can it be provided to Huawei?
The changes experienced by Huawei chips are obvious to all. If it is placed in any national enterprise in the world, it may not be 100% guaranteed not to be affected.
Because the lack of spare parts products needs to be solved by the global supply chain, it is not difficult to realize localization and self-sufficiency if it is only ordinary equipment. However, from design to production, chips are inseparable from the support of global technology.
Huawei can be responsible for the design, but it needs to rely on the supply of other manufacturers in manufacturing. The key is to use American technology, which makes Huawei unable to use 5G mobile phones. Among them, a lot of RF chips are needed, and the main market is in the hands of foreign suppliers. But if domestic manufacturers can speed up the research and development of independent RF chips, doesn't it mean that breakthroughs are expected?
Good news came from a domestic enterprise involved in the research and development of RF chips, which released key chip products and achieved a breakthrough in localization from 0 to 1. What the hell is going on? What kind of chip products did this company bring?
It is reported that this company named Litong Communication is a leading RF transceiver chip research manufacturer in China, and its released product is a RF transceiver chip supporting 200MHz broadband, with the chip model B20.
According to Litong Communication, this RF transceiver chip supports 5G applications. At the same time, the research and development chip field is a blank short board field in China, which plays an important role in the technical research and development of domestic wireless communication RF units. Litong Communication has achieved chip release in this field, which is undoubtedly a breakthrough.
The displayed performance is not inferior to the industry level, and the test data is in line with expectations.
Litong Communication has brought self-developed RF transceiver chip products, which can also be used in various application fields. Its performance is at the international level, and the test data meets the expected requirements. All in all, does it mean that Huawei has waited for the needed RF chip? Or can this chip of Litong Communication be supplied to Huawei?
The stronger the strength of domestic RF chip manufacturers and the greater the breakthrough, the higher the possibility that Huawei will solve the problem of 5G RF chips. Therefore, whenever there is good news about the breakthrough of RF chips in China, most people will think of Huawei for the first time and want to know what help these breakthroughs can bring to Huawei.
This is understandable, after all, foreign technology can't be counted on, and we can only rely on domestic technology. However, there is still suspense whether the RF transceiver chip of Litong Communication can provide corresponding help for Huawei's supply.
Because when we specifically understand the cooperation scope of Litong Communication and the usage scenario of B20, we will find that there are some deviations from the 5G mobile phone RF chip needed by Huawei. What do you mean?
In other words, the main business market customers of Litong Communication are some base station manufacturers and operators. The supplied RF transceiver chips are mostly used for private networks and special terminal equipment.
In the communication industry, many components are needed to support signal transmission and connect frequency bands. Only RF chips have transceivers, filters and other different subfields. Some are used for smart mobile terminals of mobile phones, and some support base station facilities.
Litong Communication uses self-developed RF transceiver chips in the Internet of Things, base stations and various communication transceiver scenarios, so that these application scenarios support 5G networks.
These application scenarios may be in two different directions for the RF chip components needed by Huawei. Whether it can be supplied, I believe everyone has an answer.
As the main industrial branch in the field of communication, RF chip bears the underlying guarantee of communication technology. Huawei has developed baseband chips, but because RF chips cover too many categories, the number of RF chips used by a 5G mobile phone is about twice that of a 4G mobile phone.
The seemingly tiny and easily overlooked RF chip can play an important role. However, it is difficult to realize independent design of all RF chips. Therefore, Huawei needs the support of industrial chain, and it is a domestic industrial chain.
Fortunately, domestic RF chips have been breached, including Zhuo Shengwei, Fuman Microelectronics, Jin Xinnuo, etc., all of which are accelerating and developing high-end filters, power amplifiers, RF switches and other technical research within their respective research scope.
Everything takes time, and the current R&D accumulation is to prepare for future breakthroughs. The experience of Huawei's 5G mobile phone has also made more domestic manufacturers realize the importance of independent technology. I believe that there will be a break, and Huawei's 5G mobile phone will return sooner or later.
The domestic enterprise Litong Communication released the key RF transceiver chip B20. Although the application field is not in line with Huawei's needs, it is also a happy thing for the domestic RF communication industry. I hope there will be more and more good news about this breakthrough, so that domestic RF chips will rise as soon as possible.
