() |
Abstract: |
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. |
