摘要:
我们迈着轻快的步伐走进了二十一世纪,随之而临的是,手机像日常消费品一样走进了千家万户,走进了我们的生活。去年,我国国内生产手机11929万部,内销7617万部。目前,我国手机用户已经超过3亿,已经成全球最大的手机市场。但是,我们国家对手机制造最核心的也是最昂贵的部件——手机芯片却没有拥有自己的技术,所从事的还仅仅是低廉的代工任务。因此,手机制造业里面绝大部分的利润都是被拥有核心技术的芯片生产厂商拿去。为了使我国从手机制造大国转变为制造强国,我们就必须掌握好核心技术,拥有完全属于我们自己的手机芯片!
本文以四月二十七号展讯推出的第一款3G中国芯为介入点,首先介绍了我国国内手机主板芯片的发展现状,并通过对中国芯的简要介绍,指出了我国第一款3G芯片推出的战略意义。其次,对我国国产而使用国外技术的一款手机主板芯片的主要性能和技术指标进行了简单的介绍。本文的第二章对主板的系统结构及一些关键元件进行了系统的介绍,包括数字基带处理芯片、音频基带处理芯片、电源管理芯片、射频主芯片以及存储器芯片。然后在本文的第三章,我们在参考S168一些芯片的基础上,对芯片中的一些基本元件放大器、滤波器和混频器进行了简单的原理上的设计。

Abstract:
It is the 21 century ,the mobile phone now has coming into our lives as the daily consumer. Last year , the yield of phone is 11029 in our country and there is 6817 of the mobile phones which are saled to ourselves. Up to now ,over 3 billion chinese people have their mobile phones . China has become the largest mobile phone market. However,we have not owned the pivotal technology of the chip , which is the most important part in the mobile phone ,and also is the most expensive one.We only do it for others. So the chip factories earn the most of the profit. To make our country become more and more strong in the industry of mobile phone ,we must own the critical technology and ourselve’s mobile phone chip.
In April of twenty seven , the first 3G chip of China is created by Zhanxun in Shanghai.Involving this chip,this article introduces the development of the mobile phone chip in our country , and points out the strategic meaning of the 3G chip,then introduces the function and the technology index of a phone ,which has the chip of other country but made in China. The second part of this article makes a systemic introduction of the chip’s systemic structure and some key element--including figure base bandchip, audio frequency baseband chip, power manager chip, RF basal chip and Flash Memory chip. Finally,refer to the results of some chip of S168,this article makes a theory-introduction on amplifier, filter and mixer.
 
Key Words:
Mobile Phone Chip                   Figure Baseband Chip    
Audio Frequency Baseband Chip       Mixer
