山寨手机的兴起,离不开MTK(联发科)。MTK为手机制造提供了一揽子解决方案,其中既包括硬件,也包括软件。软件方面最重要的,是操作系统。MTK方
案的软件的稳定性非常高,一方面是因为其硬件系统变化不大,另一方面,得益于MTK在系统软件上投入的巨额的资金和大量的人力。MTK采用的操作系统是
Nucleus
RTOS。Nucleus的优势主要在于占用CPU时间短,以及占用Memory空间少。随着手机硬件的发展,Nucleus的优势不再那么重要,而日益
突出的问题,是需要功能更强大的手机操作系统。 2007年11月,Google发布Android OS,剑指手机操作系统市...

据台湾媒体报道,中国台湾目前最大、全球产能排行第三的砷化镓晶圆厂稳懋,今年在市场需求大增下获利丰厚,2009年第三季度盈利接近3亿元新台币,并可望维持此种高利润趋势。公司内部预估全年营收可达48亿新台币,较去年增长3成。
受3G和智能手机需求增长,砷化镓用量大增 砷化镓主要应用于射频通讯元件,主要产品包括功率放大器(PA)、射频开关(RF
Switch)等。稳懋微波事业群总经理王郁琦指出,在2G手机上,仅使用1~2颗功率放大器与射频开关器,但3G、智能手机用量提高至4~6颗,因此市场需求大增,导致砷化镓今年产品紧缺,价...

high emphasis on profitability in fiscal 2010 and beyond, we
concluded that we could no longer continue to support our
significant investment in RF measurement products, and should
instead focus on growing our core business, stated Joseph P.
