Infineon Technologies AG announced that it had started volume shipments of its GSM/GPRS RF transceivers manufactured in standard CMOS technology to a tier 1 customer.

The new SMARTi SD is claimed by the company to be the world's first single chip CMOS-based GSM/GPRS quad-band transceiver that is optimized for cost, size and power consumption. It integrates into one chip all the functions required by a GSM radio, including an RF VCO, Zero IF receiver and Sigma-Delta transmitter chain, and enables global roaming, making possible small inexpensive devices that combine a mobile telephone with web browsing capabilities.

According to Dominik Bilo, Chief Marketing Officer of Infineon's Secure Mobile Solutions business group, "an integrated CMOS GSM/GPRS RF transceiver has been a goal of the industry for many years."

A member of Infineon's SMARTi product line, the RF transceiver is the first product that uses 0.13?m standard CMOS process technology. Its fast locking time and low power consumption makes it a suitable solution for GPRS class 12 implementation, as well as low-cost, voice-only phones. The SMARTi SD is entirely controllable through a 3 wire bus and is housed in a VQFN-48 standard package.

50 percent less board space

Infineon shared that a GSM/GPRS radio using SMARTi SD can be implemented with 50 percent less board space and saves 30 percent in components' cost compared to competing solutions. The high integration level enables OEMs and ODMs to speed up development time and save R&D costs, the company added.

Additional information on the product can be found online.
