    Huaqi released the first volume of Full B41 BAW filters in China

     

    According to Mike consultation, recently, the Full B41 BAW filter flow of 5G mobile phones, which is independently developed by Huaqi Wireless Technology (Shenzhen) Co., Ltd. is successful, and will enter the mass production phase. This is another result of the 5G BAW filter in domestic chip technology, which is beneficial to promote the accelerated development of the chip. The filter plays an eliminating interference signal in the mobile communication network to filter out the noise to achieve precision saver. As a technical representative in the communication industry, the BAW filter is high, and the sound energy density is high, the structure can be well defined sound waves, so the high frequency signal is usually selected with the BAW filter. Hua Yixin this downtown BAW filter, bandwidth reaches 194MHz, and supports the implementation of Power Class2 standards, and all parameters have reached the international similar product level; not only meets 160MHz bandwidth requirements of China Mobile, but also can apply to global Market. The successful flow of Huaye Full B41 BAW, marking another representative China Manufacturing Filter chip has been successfully developed. The filter is the most challenging module in the front end of the RF. In the market, the BAW filter is more difficult, and the difficulty is difficult, and the cost is higher. In China, the number of manufacturers that have the ability to enter this area is small, so the BAW filter is more scarce in the market. Dr. Liang Haiyang, chairman of Huaqi Wireless Technology, said: "For BAW filters, only samples do not go to large-scale mass production; but want to do production, even if it is only 3%, The yield of forty is very difficult. "The Full B41 BAW filter of this Huaqi successful flow film has been developed and trials for many years, and finally breaks through the technical bottleneck, and the product will enter from the engineering stage. Section. 5G era has brought huge market opportunities for the filter industry, there will be more frequency band resources to be put into use, and the increase in frequency band will cause the filter to continue to be upgraded, and the amount of the filter is greatly improved. As an important sector in the radio front market, the BAW filter will be the main force of the 5G era. In the past a long time, the radio front end is monopolized by several giants in the US Japan, and it has more market voice, and manufacturing costs are also more low. For Chinese companies, the technological accumulation in the field of filter is slightly weak. In recent years, China RF front-end chip manufacturers gradually show in the world market. For the future prospects of the BAW filter, General Manager He Jingjing said: "Huayin will make the layout of the full-range section of the filter, which can cover China Mobile, China Unicom, China Telecom, and Japan, Europe, the United States, etc. " As a rapidly developing China Semiconductor Manufacturing Manufacturers, China has a rich experience in filter design and process manufacturing, and has made key breakthroughs in product architecture and process processes, with absolute independent intellectual property rights. Since 2018, Huaqi Wireless has launched a deep cooperation with the world's leading radiofrequency wafer plant. Huaqi's corporate architecture As a professional RF chip, it is designed to provide high-quality product services and technical support for end users and communication modules, to promote the progress and development of the RF industry. Huaqi will make full use of its own material technology advantages and customer platform advantages, expand high-end RF devices in 5G era, and maintain the leadership of the company in the field of radio devices. Following the Full B41 BAW successful flow, Hua He is expected to provide a filter chip sample suitable for providing N77, N78, N79, etc. at the end of 2020. Sample suitable for filter chip samples suitable for China 5G band. Reprinted from MEMS.
