Jingxun launches new filter products again, vowing to break the monopoly of the United States and Japan

According to a Yole Development report, the overall RF front-end market size for mobile devices and WiFi connections will grow from $15 billion in 2017 to $35 billion in 2023, with a compound annual growth rate of 14%. Among them, filters, the largest market for RF front-ends, will grow about three times from 2017 to 2023, with a compound annual growth rate of 19%.

At present, the RF filter chip market is mainly monopolized by international giants from the United States and Japan, such as Broadcom, Skyworks, Qorvo, and Murata, and the domestic self-sufficiency rate is relatively low.

Recently, Jingxun Juzhen Technology Co., Ltd. (abbreviated as Jingxun) officially released its independently developed B41 full-band FBAR filter and B40 filter in Zhuhai.

According to Jingxun, the FBAR filter launched this time uses original single-crystal doped piezoelectric materials and single-crystal thin-film electrode technology, which can redefine the performance of FBAR resonators and filters, and innovatively invent a new low-cost wafer-level Bump-on-Via WLP packaging technology. The SC-FBAR filter designed and produced using the above technology can reduce the package size while supporting high power, and has the industry's thinnest WLP package, large bandwidth, high out-of-band suppression, and low insertion loss. Both B41 and B40 filters do not require additional external matching. 

In addition, Jingxun revealed that it will release high-performance 5G n79 filters, n77+n79 diplexers and a low-cost, high-performance B3 duplexer in Q3 2020; and will release the B1+B3 quadplexer in Q4 2020.

Jingxun was founded in 2017 by industry leader Dror Hurvits in Zhuhai. It is the only high-performance FBAR filter IDM manufacturer in China with multiple US patents. Jingxun has obtained 9 US invention patents and 19 US and Chinese patent applications are under review. Its patent pool covers filter design, resonator structure, packaging methods and manufacturing. In the next 18 months, the number of Jingxun patents will double. In the 5G era, Jingxun can provide world-class high-performance SC-FBAR filters, duplexers and multiplexers for mobile phones, modules, smart terminals and small base station customers.

It is reported that Jingxun's advanced process center for R&D and production in Tianjin is the only semiconductor factory in the world that has the ability to epitaxially dope piezoelectric films and electrode films, and has excellent mass production trimming capabilities. Jingxun's current 6-inch wafer production capacity can reach 1,500 pieces/month, and will be expanded to 5,000 pieces/month in the second half of 2020.

It is worth noting that under the background of domestic substitution, domestic RF front-end chip manufacturers have also ushered in a good opportunity for development. According to Jingxun, continuous innovation and accumulation of intellectual property rights have allowed Jingxun to break through the patent and technology monopoly of American and Japanese companies on BAW/FBAR filters, and also obtained investment from leading domestic semiconductor companies, industrial funds and listed companies.
