Fast Technology News on April 16, according to Wenzhou official news, the annual production of 120,000 pieces of 5G RF filter silicon-based wafer project has been signed and settled in Wenzhou Bay New District, and the first wafer factory in Wenzhou is about to be born.
It is understood that semiconductors are the supporting technology that promotes the digitization of everything. A chip is a semi-finished product cut from a wafer, and the wafer is the carrier of the chip. The signed 5G RF filter silicon-based wafer project is an important part of Zhejiang Xingyao Semiconductor Co., Ltd.’s realization of RF filter chips from independent design to independent production.
Star Semiconductor settled in Wenzhou Bay New District in 2020. After nearly three years of hard work by the technical team, it has successfully developed a series of domestic advanced products such as BAW WiFi 6E and n79F filter chips. It has more than 50 patents and has great development potential. huge.
A radio frequency filter is a device that can filter out out-of-band interference and noise to meet the signal-to-noise ratio requirements of radio frequency systems and communication protocols.
The number of frequency bands that smartphones need to support under 5G is constantly increasing, because not only must they be compatible with 4G frequency bands, but also support 5G frequency bands to meet the needs of 4G and 5G multi-mode signal switching.
This also means that a 5G mobile phone in the future will need hundreds of filters. At present, a 4G mobile phone needs to use more than 30 filters.
