About GaN Feature Introduce
The growing demand for high-speed, high-temperature and high power-handling capabilities has madethe semiconductor industry rethink the choice of materials used as semiconductors. For instance,
as various faster and smaller computing devices arise, the use of silicon is making it difficult to sustain Moore’s Law. But also in power electronics, So GaN semiconductor wafer is grown out for the need.
Due to its unique characteristics (high maximum current, high breakdown voltage, and high switching frequency), Gallium Nitride GaN is the unique material of choice to solve energy problems of the future. GaN based systems have higher power efficiency, thus reducing power losses, switch at higher frequency, thus reducing size and weight.
GaN technology is used in numerous high-power applications such as industrial, consumer and server power supplies, solar, AC drive and UPS inverters, and hybrid and electric cars. Furthermore,
GaN is ideally suited for RF applications such as cellular base stations, radars and cable TV
infrastructure in the networking, aerospace and defense sectors, thanks to its high breakdown strength,low noise figure and high linearity.
