Abstract :
This work describes the first multiband WCDMA/HSPA/EGPRS single-chip transceiver with GPS and receiver diversity. This device supports UMTS bands 1,2,3,4,5,6,8,9,10 and GSM/EDGE 800, 900, 1800, 1900 MHz bands. It is implemented in cost-effective 0.18 mum RF CMOS technology and uses a reduced number of TX and RX SAW filters.
