Single chip CMOS GSM/GPRS radio transceiver

11 August 2004 Telecoms, Datacoms, Wireless, IoT Integrated Solutions

Infineon Technologies has started volume shipments of its new SMARTi SD, said to be the world's first single chip CMOS-based GSM/GPRS quad-band transceiver. Optimised for cost, size and power consumption, it integrates into one chip all the functions required by a GSM radio and enables global roaming, making possible small inexpensive devices that combine a mobile telephone with Web browsing capabilities. SMARTi SD is a member of Infineon's successful SMARTi product line. A GSM/GPRS radio using SMARTi SD can be implemented with 50% less board space and saves 30% in components' cost compared to standard solutions, claims Infineon. An integrated CMOS GSM/GPRS RF transceiver has been a goal of the industry for many years. The SMARTi SD integrates into a single chip all functions required of a GSM/GPRS quad-band transceiver, including an RF VCO, zero IF receiver and sigma-delta transmitter chain.
