We have developed 28V-operation high voltage GaAs and 50V-operation GaN devices and successfully moved to mass-production. Our flexible wafer process line utilizing Light-Wave products process line can handle small size SiC wafers the same as the matured 4-inch GaAs wafer process line. The device performance of high Voltage GaAs and GaN devices from mass-production line is well controlled. We have released full line-ups for W-CDMA and WiMAX base station systems from 10W to 180W devices as products from mass-production line.
