This radio integrates all the receive and transmit functions required to support a quad-band GSM/GPRS/EDGE application into a single CMOS chip. Compared to the published work, this transceiver is implemented in low-cost digital 0.13 mum CMOS, achieves a superior receive and transmit performance, and yet has up to 2x lower receive power consumption, a key requirement in cellular applications.
