Spreadtrum Announces World's First TD-SCDMA/HSDPA/EDGE/GPRS/GSM Single-Chip RF Transceiver



BARCELONA, Spain, February 16 --

-- The QS3200 RF Transceiver Features High Integration and Low Power Consumption and Provides 2G/2.5G/3G/3.5G Multimode Support

Spreadtrum Communications, Inc. (Nasdaq: SPRD) (the "Company"), one of China's leading wireless baseband chipset providers, today announced its new RF transceiver solution, the QS3200, the world's first single-chip RF transceiver to support TD-SCDMA/HSDPA/EDGE/GPRS/GSM standards during the 2009 GSMA Mobile World Congress. Followed by the GSM/GPRS single-chip RF transceiver, the QS500, and the GSM/GPRS/EDGE single-chip RF transceiver, the QS1000, today Spreadtrum announced the QS3200, the world's first single-chip RF transceiver to support multimode such as 2G/3G/3.5G. The QS3200 offers great improvement over the other TD-SCDMA RF chip on signal transmission, reception, and power amplification in addition to the integrated features and low power consumption in Spreadtrum's other chip solutions. The launch of the QS3200 makes Spreadtrum one of the total solution providers in the wireless communications market and takes a positive step forward in commercializing TD-SCDMA technology. Spreadtrum will showcase the QS3200 product at its business hospitality suite, Hall 4 Level 4 Stand 4.4HS50.

High integration and cost-effective RF solution

The QS3200 is a dual-band TD-SCDMA and a quad-band EDGE transceiver. Implemented in low cost, bulk CMOS, it is optimized to meet the challenges of today's small form factor, power efficient, high performance cellular handsets.

Currently smallest TD-SCDMA/EDGE RF transceiver

The QS3200 is available in a 9mm x 9mm QFN64 package. Owing to its single-chip design, the size of the PCB using the QS3200 solution can be smaller than 600 mm2.

Excellent RF Performance

The QS3200 supports HSDPA and HSUPA, and it exceeds all requirements of 3GPP TS 25.102.

The TX EVM (Error Vector Magnitude) for TD-SCDMA HSPA <3% and the RX EVM for TD-SCDMA HSPA <5%.

Support external host chipsets

It supports a wide range of external front end components including the entire family of SC8800 series dual mode baseband and other TD-SCDMA basebands. SPI control interface is used in the QS3200. Both analog I/Q as well as LVDS interfaces are supported in the TD system. Analog I/Q is supported in the GSM system.

About shipment

The QS3200 chip is sampling now and is expected to be available in commercial quantity in the second quarter of this year.
