GaAs器件技术刚由军事应用向民用转化,正逢世界移动通信发展热潮,也一跃为热门技术。移动通信用手机已成为普通百姓的通信工具,生产量急剧攀升,GaAs器件一度成为紧俏产品,甚至在市场上脱销。 急需镓砷器件 当今世界移动通信发展迅猛,GSM阵营小步快跑,115kbps通用包交换无线服务GPRS(General Packet Radio Serverce)在全球各地刚开始,又通过384kbps的EDGE过渡正逐步向宽带第3代移动通信系统UMTS(Universal Mobile Telecommunication)迈进;
GaAs device technology has just been transformed from military applications to civilian use, coinciding with the upsurge of mobile communications development in the world, but also became popular technology. Mobile phones have become common people’s communications tools, production rose sharply, GaAs devices became a tight product, and even out of stock in the market. Urgent need of gallium arsenide devices The rapid development of mobile communications in the world today, GSM camp small run, 115kbps General Packet Radio Services (GPRS) General Packet Radio Serverce began around the world, and through 384kbps EDGE transition is gradually to the third generation of broadband Mobile Communications System UMTS (Universal Mobile Telecommunication) forward;
