Officially released autonomously developed B41 full-band FBAR filter and B40 filter, breaking US-Japanese patents and technology monopoly

Recently, Crystal Chunzheng Technology Co., Ltd. officially issued its autonomous B41 full-band FBAR filter and B40 filter in Zhuhai. According to Jingxun, the original single crystal doped piezoelectric material and single crystal thin film electrode technology of the FBAR filter, which can redefine the FBAR resonator and filter performance while innovative inventions have a new low-cost crystal. Circular Bump-on-VIA WLP Packaging Technology. The SC-FBAR filter designed by the above technique can reduce the package size while supporting high power, has excellent properties such as the thinner WLP package, large bandwidth, high bandwise suppression and low insert loss. B41, B40 filter do not require additional external matching. In addition, crystal news revealed that high-performance 5G N79 filters in 2020, N77 + N79 co-directional duplexer and a low-cost high-performance B3 duplexer; in 2020 Q4 released B1 + B3 four-worker . Jixun was established in 2017. DROR HURVITS is founded in Zhuhai, which is the only high-performance FBAR filter IDM manufacturer with a number of US patents. Chunxun has obtained nine US invention patent licenses, and there are 19 US and Chinese patent applications are under approval; its patented pool covers filter design, resonator structure, packaging methods and production and manufacturing, etc.; in the next 18 months Inside, the number of crystal news patents will be doubled. 5G era, crystal news can provide world-class high-performance SC-FBAR filters, duplexers and multi-workers for mobile phones, modules, intelligent terminals and small base stations customers. It is reported that crystal news is the only advanced process center for R & D and production in Tianjin, which is the only semiconductor factory with extensive fluid-fluid-filled film and electrode film capabilities. It has excellent production of Trimming capabilities. Crystal news currently 6-inch crystal can reach 1500 pieces / month, and will extend to 5,000 pieces / month in the second half of 2020. According to Yole Development, the overall RF front-end market scale will increase from $ 15 billion in 2017 to $ 35 billion in 2017, an annual composite growth rate of 14%. Among them, the largest market in the front end of the radio frequency will increase by about 3 times from 2017 to 2023, and the compound growth rate reaches 19%. At present, the current RF filter chip market is mainly monopolized by Broadcom, Skyworks, Qorvo, Village and other US Japan, with a low domestic self-sufficient rate. It is worth noting that in the context of domestic alternatives, domestic RF front-end chip manufacturers also usher in a good development time. According to Jingxun, sustained innovation and intellectual property accumulation allows Juxians to break through the patents and technical monopoly of the BAW / FBAR filter, and has also gained investment in China's leading semiconductor companies, industrial funds and listed companies.
