Abstract

Engineering Engineering, Electrical & Electronic Optics Physical Sciences Physics Physics, Applied Science & Technology Technology Telecommunications
In this paper, novel RF front-ends for GSM/W-CDMA dual band and dual mode mobile terminal are described. The zero IF direct modulation transmitter and duel-superheterodyne receiver have been realized in the RF module development. The power down functions of IC chip used to switch the RF module turn on W-CDMA mode or GSM. The testing results are shown both for the W-CDMA and GSM modes finally.
