Cree (Durham, NC) reports it has surpassed a significant milestone in shipping over two million GaN High Electron Mobility Transistors (HEMT) for cellular telecommunications and is providing game-changing benefits over traditional silicon-based technologies, including higher power, higher efficiency and wider bandwidth. As mobile devices such as smartphones are becoming more widespread, telecommunications companies are looking for innovative technologies to improve channel capacity and speed of wireless systems, while simultaneously lowering power consumption of transmission amplifiers. The use of GaN HEMT in transmitter amplifiers is gaining attention in the cellular telecommunications industry due to the ability to decrease power consumption and size, and increase bandwidth capabilities.
The next-generation performance enabled by Cree GaN HEMT are required to support today’s 4G LTE cellular networks, as well as to help drive LTE release 10 and advanced LTE networks currently being developed. The superior efficiency and bandwidth advantages of GaN HEMTs help LTE cellular network transmitters achieve smaller size, lower weight and improved thermal management compared with incumbent technologies. Features include:
- Data channel bandwidths over 100MHz.
- Wide instantaneous RF bandwidths, helping operators aggregate multiple, non-adjacent frequencies.
- Improved transmitter efficiency offers energy savings for operating budgets.
