This tiny radio chip could supercharge future phones with 6G speeds
- Researchers in Japan developed a tiny radio module for faster and more efficient mobile devices.
- The module is aimed at enhancing 6G wireless technology, offering higher speeds than current 5G networks.
- Operates at 150 GHz in the D-band with significant bandwidth potential for faster data transmission.
- Traditional use of D-band technology was limited due to signal degradation and power consumption issues.
- The new module created by Professor Kenichi Okada's team is compact and energy-efficient at 8.4 mm by 20 mm in size.
- Capable of reaching 56 Gbps speeds using only 150 milliwatts of power per antenna.
- Innovative design includes efficient phase shifting and signal mixing techniques.
- Special mixer and phase shifter reduce interference and eliminate the need for extra components that consume power and space.
- Antennas and amplifiers are optimized to work together seamlessly, improving system efficiency.
- Presented at the 2025 Symposium on VLSI Technology and Circuits for its potential to enable super-fast 6G connections in compact devices.
- The technology could empower future phones and wearables to support high-speed applications with improved performance and lower power consumption.
- Potential applications include mobile virtual reality, advanced medical tools, and industrial automation.
- Overall, this tiny radio chip could pave the way for bringing advanced 6G capabilities to handheld devices.
