First All-Frequency 6G Chipset
A team of researchers from Peking University and the City University of Hong Kong have developed the world’s first 6G chipset capable of operating across an ultra-wide frequency band ranging from 0.5 GHz to 115 GHz. Unlike current wireless systems that require multiple radio subsystems, this single device can reconfigure itself to handle the entire spectrum needed for next-generation 6G connectivity.
This flexibility makes it uniquely positioned to power a variety of applications, from high-speed mobile internet to ultra-low latency communications, and even AI-driven network management that automatically optimizes performance in real time.
Revolutionary Thin-Film Lithium Niobate (TFLN) Technology
Central to this innovation is the use of a new material—thin-film lithium niobate (TFLN)—which allows compact and efficient photonic integration on the chip. The chipset measures only 11 x 1.7 mm yet integrates a broadband electro-optic modulator that converts wireless signals into optical waves, enabling fast and stable signal generation and transmission.
The TFLN platform merges electrical and optical signal processing, dramatically enhancing frequency modulation and signal quality across microwave, millimeter-wave, and terahertz bands. Experimental tests revealed the chipset could tune frequencies as fast as 180 microseconds, showcasing rapid adaptability essential for dynamic wireless environments.

Implications for 6G and Beyond
While the chipset represents a foundational advancement toward 6G, various challenges lie ahead for mass adoption, including real-world field testing to prove durability and performance under diverse conditions. Beyond the chip itself, building a sustainable 6G ecosystem will require compatible devices, infrastructure, and global standards development.
This research primarily aims at enabling future mobile networks to handle exploding data demands with more efficiency and reliability, potentially transforming everything from personal internet use to critical industrial and automotive applications.
The unveiling of this all-frequency 6G chipset built on thin-film lithium niobate technology is a significant milestone in telecommunications. It introduces a paradigm shift toward highly adaptive, ultra-broadband wireless networks capable of supporting the next wave of mobile innovations at blistering speeds and minimal latency.
As development progresses, this technological leap could redefine how we connect, communicate, and operate in an increasingly digital and AI-driven world.
