Researchers at the University of California, Davis (UC Davis) have developed a high-frequency electronic chip that has the potential to transmit tens of gigabits of data every second, much faster than the fastest Internet connections today.

The researchers designed the chip using a phased-array antenna system, which funnels the energy from multiple sources into a single beam, which can be narrowly steered and directed to a specific location. The researchers found the chip successfully operates at 370 GHz with 52 GHz of bandwidth.

"As we continue to migrate to systems like cloud computing and next-generation cellular networks, the need for speed is growing," says UC Davis professor Omeed Momeni. "Higher frequencies mean more bandwidth and more bandwidth means higher data rate."

Momeni notes the new technology demonstrates it is possible to harness the large available bandwidth at millimeter-wave and terahertz bands on a single, compact chip.
