On June 22, domestic RF chip manufacturers - Feiyi science and technology announced that after two years of full development, it officially released a complete 5G RF front-end program in June 2020, achieving two first: first set of integrity Support all 5G frequency front-end solutions and first sets of RF front end modules with 5G performance using domestic processes.
According to reports, the 5G RF front-end solution launched by Feiyi Technology is a complete range of RF chip products, including:
If FX6779 / FX6777 / FX6728 / FX6777 / FX6728 / FX6727 and other products can be fully satisfied with any 5G NR application such as SUB-6GHz band 1T4R, 2T4R or the like; in the SUB-3GHz band, FX6241 and FX5627H can overwrite all bands, while combining satisfaction EN-DC application requirements; 6 5G switches fully cover all 5G switch application scenarios and provide a speed switching speed below 2us.
Feiyi Technology said that the core process of RF front end is a gallium arsenide. As a radio frequency device manufacturer of deep-moving domestic supply chain, on the basis of ensuring performance, guarantee quality, has been adhering to the use of domestic manufacturers San'an Optoelectronics Process manufacturing. In the 4G era, Feiyi Technology has been shipped with billion radio frequency chips using domestic processes. Today, after the close cooperation and joint efforts of San'an, Feiyi Technology took the lead in achieving 5G performance in the domestic three-security process, and the above 5G RF product has fully used San'an arsenide process. Feiyi Technology emphasizes that 5G products are completely based on autonomous research and development of invention patents and proprietary technology.
According to the data, the radio frequency front end device mainly includes radio frequency switches and LNA, radio frequency PA, filter, antenna Tuner, and millimeters wave, including about 50% of the sales of RF device, and RF PA account for about 30%, radio frequency switch. And LNA accounts for about 10%, and other accounts for approximately 10%), and foreign manufacturers still occupy great advantages.
According to the data of the research institution, 93% of the world's 93% of the PA is now concentrated in several manufacturers such as Skyworks, Qorvo and Broadcomm. The filter is also divided by Murata, TDK, TAIYO Yuden, Avago and qorvo, in which Murata, TDK and Taiyo Yuden scored 80% SAW filter, while Qorvo and Broadcomm occupied 95% of the BAW market.
In the 4G Pa, there is only the only cent of the core, and it has been acquired by Lianfa, and the Han Dynasty, Feiyi Technology. Domestic SAW filter manufacturers have mainly 55, 26, Wuxi, BAW filter domestic manufacturers have Tianjin Ni Si. In terms of radio frequency switch, there is Zhuo Sheng Micro (Samsung and Xiaomi is the biggest customer), Zhu Rui, Well Shares, Deqing Huaying, etc.
Since the PA chip is costly cost, it is necessary to use semiconductor technology such as GaaS, GaN, SiC on high-end RF devices, and there are fewer domestic mature suppliers. Skyworks, Qorvo, Broadcom, Murata and other major plants mainly use IDM models to produce themselves. The main foundry of the PA chip is also concentrated in Taiwan, China, and most communists have a steady foundation for arsenide gallide. The domestic PA wafer foundry is mainly San'an Optoelectronics.
It is worth mentioning that San'an has already developed the main gallium gallium gallium gallium gallium PA chip by investing in San'an, which has become the main arsenide material of the mainland, which has become the first part of the mainland to produce compound semiconductor. At the end of 2017, San'an Optoelectronics made RMB 33.3 billion (about NT $ 1,46.1 billion), invested three-five compound semiconductor materials in Nan'an High-tech Industrial Park in Quanzhou, Fujian Province. Last year, San'an increased capital movements frequently, cumulative cash has been implemented for about 15 billion yuan, which also enables San'an Optoelectronics to have sufficient funds for compound semiconductors, and 5G RF front-end chip has a good preparation.
With the development of the smartphone industry, it is also increasingly high for RF frontal integration. Especially in the field of 5G RF front-end devices, since more power is required, higher power is required, and the number of frequency bands that need to be supported (because not only 4G frequency band, 5G band is also supported to address 4G, 5G multimode signal) Demand for switching), for the technical complexity requirements and quantity requirements of components such as PA, RF switch, and filters, are also getting higher and higher. Therefore, domestic manufacturers who have been able to provide 5G RF front-end solutions.
As a domestic old radiofrequency front-end chip manufacturer, Feiyi Technology is a National Technology Wireless RF Division, has 10 years of R & D and sales history of RF front-end products. Feiyi Technology was the first domestic manufacturer of 4G PA. In 2015, millions of shipments were achieved on the red rice mobile phone. In December last year, Feiyi Technology announced the completion of more than 100 million yuan B + round financing, which was hoped by Zhongjin Capital and Yuanhe. Previously, Feiyi Technology has also been diligent, Shenzhen Gaoxin, Shenzhen Petronomical Investment, Dandelion Investment, Hongxin Entrepreneurship Workshop, Multi-wheel Investment in Yunchuang Capital.
This time, Feiyi Technology successfully launched a complete domestic RF front-end solution that supports all 5G bands, it can be said that it has successfully filled the domestic gap. Moreover, the 5G RF front-end module of Feiyi Technology is also the first set of arsenide process with domestic Sanan Optoelectronics to achieve 5G RF front-end module, which means that the 5G RF front-end module of Feiyi Technology is a complete domestic.
