Abstract
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 the IC chip used to switch the RF module turn on the W-CDMA or GSM mode. Finally, the testing results are shown for both the W-CDMA and GSM modes.
