Ultracompact 2G/3G Dual-Mode RF Transceiver IC for Mobile Phones and 3G Communication Cards for PCs
Renesas Technology has announced the R2A60281LG, an ultra-compact 2G/3G dual-mode radio frequency (RF) transceiver IC that supports both 2G and 3G modes used in cellular communications. The device integrates in a single chip most of the high-frequency signal processing functions required by mobile phone handsets. Sample shipments will begin in March 2008 in Japan.The
The R2A60281LG integrates 2G (GPRS/EDGE) quad-band (850 MHz/900 MHz/1.8 GHz/1.9 GHz) and 3G (W-CDMA) quad-band (800 MHz/1.5 GHz/1.7 GHz/2 GHz) functionality into a single chip. It also supports HSDPA*1 categories 7 and 8 (maximum. 7.2 Mbps), allowing high-speed data downloads along with support for global standards.
Approximately 20% smaller mounting area than previous RF transceiver ICs from Renesas Technology
In addition to the features mentioned above, the R2A60281LG integrates a low-noise amplifier (LNA) and other functions. It combines all high-frequency signal processing functions other than antenna switching in a single chip in a thin and compact package (7 × 7 × 0.60 mm) that has a mounting area approximately 20% smaller than previous RF transceiver ICs from Renesas Technology.
The R2A60281LG implements A/D and D/A conversion functions formerly handled by an analog baseband processor. It includes a high-speed (maximum 312 Mbps) digital interface function that enables high-speed exchange of I/Q and control data with a digital baseband processor, making possible high-speed transfer of large data volumes. Since no analog baseband processor is necessary, the combined mounting area is reduced.
