An integrated RF front-end for multi-mode handsets

Multi-mode and multi-band communication networks have emerged as a step towards true 3/sup rd/ Generation (3G) networks. In this paper, novel integrated RF front-ends for multi-mode/band handsets are described. The advantages of an integrated front-end are demonstrated by measurement results of a prototype EGSM/PCS front-end module. It is shown that this integrated RF module offers a substantial improvement in the present state of handset design.
