Major breakthrough in UWB technology

Major breakthrough in UWB technology 

Recently, Changsha Chixin Semiconductor Technology Co., Ltd. (hereinafter referred to as "Chixin Semiconductor") has launched the first commercial UWB chip CX300 in China. The blank is of great significance to the development of UWB ecology in our country.

UWB is a wireless carrier communication technology that uses a frequency bandwidth above 1 GHz.

It does not use the sinusoidal carrier in the traditional communication system, but uses nanosecond non-sine wave narrow pulses to transmit data, so it occupies a large spectrum.

Although wireless communication is used, its data transmission rate can reach hundreds of megabits per second.

The CX300 released by Chixin Semiconductor this time is a full-featured UWB chip that supports the latest 802.15.4z standard, has a variety of low-power consumption modes, supports multi-antenna solutions, supports FIRA/CCC specifications, and positioning accuracy is in line of sight.

It can reach plus or minus 5 cm, and the angle measurement accuracy can reach plus or minus 3 degrees. Various functions, performance and power consumption indicators can meet the needs of smart home device control, digital keys, indoor positioning and other application scenarios, Which the history of UWB technology has innovative significance in China.

UWB technology can be applied in many scenarios. In addition to smart home device control, UWB technology can also have a lot of room for development in fields such as mobile phones, automobiles, the Internet of Things, and 5G positioning.

It is reported that UWB ultra-wideband technology has been developed on the industrial side for many years, and the widespread attention originated from the iPhone11 released by Apple in November 2019 that supports UWB technology. Later, Apple has introduced Apple Watch S6, HomePod mini smart speakers, and iPhone12 series mobile phones. In products such as Aritag and Aritag wireless trackers, the self-edge UWB solution is applied. In addition to Apple, there are currently international big names such as Samsung, Xiaomi, OPPO, and Vivo that are also actively deploying in the direction of UWB technology applications.

In the past few years, UWB technology has been adopted by all aspect of life, and with the efforts of experts from all aspect of life, UWB technology has made breakthrough progress, which has promoted the rapid development of mobile phone ecology, automotive digital key ecology, industrial scenes, and 5G positioning.

The grand launch of Chixin Semiconductor's first commercial UWB chip this time is undoubtedly a milestone in the history of domestic UWB technology. We look forward to faster and better development of the domestic electronics industry with the help of Chixin Semiconductor CX300.
