摘要
提出了一种按照GSMPhase2+技术规范实现的GSM移动通信手机射频收发子系统的硬件方法。该系统采用了当今较为流行的DCR方案,并且支持GPRS应用,可工作在EGSM900和DCS1800双频段上。文中介绍了射频收发子系统的构成和基本原理,描述了系统设计实现的具体过程,为系统设计提供了必要的分析和计算。
The hardware implementation of a RF subsystem of GSM mobile communication handset based on GSM Phase 2+ of technical specification is presented in this paper. The RF subsystem for dual-band(EGSM900/DCS1800)applications adopts DCR scheme which is more popular nowadays and it supports GPRS application. The structure and principle of RF subsystem is introduced. Then the specific process of design and implementation is described in detail and the necessary analysis is provided.
