当今无线通信业市场需求急增,预估到2003年全球手机使用数目将达10亿支,相当于现有的有线电话数量总和。功率放大器的市场需求量将与手机同步高速增长,到2003年,双双都将突破3亿大关。由此拉动了以砷化镓(GaAs)为材料的无线通信半导体产业,近来更吸引着以硅晶为材料的半导体业向其靠拢。 With the rapid increase in demand in the wireless communications industry today, it is estimated that by 2003, the number of global mobile phone use will reach 1 billion, equivalent to the total number of existing wired phones. The market demand for power amplifiers will grow at a rapid pace with mobile phones. By 2003, both will exceed the 300 million mark. This has led to the wireless communication semiconductor industry, which uses gallium arsenide (GaAs) as the material. Recently, it has attracted the semiconductor industry, which uses silicon crystal as its material, to move closer to it.
