Recently, there is good news in the industry, Beijing Saiwei Company has successfully mass-produced the first optical fiber waveguide filter in China, which is a major breakthrough, which not only breaks the long-term monopoly of optical fiber waveguide in developed countries such as Europe and the United States, but also demonstrates China's independent innovation ability in the field of 5G communication. 
Founded in 2008, Saiwei Technology is an enterprise specializing in the development and production of RF filter products. Through more than ten years of unremitting efforts, we have made a leap from R&D to large-scale production. It is reported that the volume acoustic wave filter produced in this batch has the advantages of high efficiency, low loss and high reliability, and all performance indicators have reached the international level. Behind these achievements are hundreds of scientific research workers, who have made breakthroughs in technical challenges again and again, and have made great contributions to the development of China's semiconductor industry. 
During this period, Zhang Hao, the founder of North Micro, also had a moving story. Zhang Hao is a doctoral student who graduated from an American university, and has been committed to the research and development of high-frequency integrated circuits since returning to China. But in 2015, he was arrested by the FBI for his involvement in a U.S. science and technology seminar, accusing him of being an economic espionage. This accident not only had a great impact on Zhang Hao himself, but also had a great impact on the development of science and technology in China. But Zhang Hao did not stop there, but embarked on the road of justice and resolutely defended his rights. At the same time, the company has also made breakthroughs in a number of technical patents, laying a solid foundation for the development of RF filtering technology in China. 
The successful mass production of Saiwei is not only an affirmation of Mr. Zhang Hao's perseverance, but also a major milestone in the history of China's semiconductor industry. According to data, by 2025, the scale of China's 5G network will reach 22 trillion, and the market share of filtration equipment will account for a large proportion. The successful implementation of this project is of great significance for the rapid development of China's 5G industry, and will also enhance China's comprehensive competitiveness in the field of 5G.
At the same time, the success of Saiwei has also enabled China to establish a strong brand with independent innovation ability in the world's science and technology competitions. Chinese enterprises and researchers have shown great courage and perseverance in dealing with some unfair and unfair practices in the international technology competition. In this process, scientists have overcome all kinds of difficulties, dared to meet challenges, unswervingly walked out of their own path, and contributed China's wisdom and strength to the development of China's science and technology.
Looking forward to the future, China will make greater progress and achievements in the field of science and technology in the world. We have every reason to believe that China will make major breakthroughs in many fields in the future, embark on a leading path, and contribute China's wisdom and strength to the development of global science and technology.
The successful mass production of 5 G filters not only broke the monopoly of 5 G filters in developed countries such as Europe and the United States, but also showed China's strong will and strong strength in scientific and technological innovation. These achievements will inspire Chinese enterprises and researchers to devote themselves more actively to scientific and technological innovation, and make unremitting efforts to achieve a scientific power.
