Rising develops RF transceiver chipset for 3G WCDMA handsets

May 30, 2006

Rising Micro Electronics announced that it has successfully developed China's first commercially available Radio Frequency (RF) transceiver chipset for 3G WCDMA wireless handsets using Jazz Semiconductor's 0.18um SiGe BiCMOS design platform. Rising's WCDMA RF transceiver chipset includes the zero IF receiver chip (RS1007W) and transmitter chip (RS1007RF), designed using Rising's intellectual property.

With the announcement of Rising's WCDMA chipset, it becomes one of the first design companies in China to demonstrate the capability of carrying out the complicated research and development work required for high-end 3G RF transceiver chip designs, closing the gap in high-end communication chip design between China and other countries. The RS1007W and RS1007RF offer a complete solution for the RF front-end chipset for 3G WCDMA wireless handsets. The RS1007W uses advanced zero IF architecture, and integrates an LNA, mixer (downconverter), AGC, LPF, Delta Sigma fractional N PLL, VCO, DC offset calibration circuit, RC calibration circuit and I/Q imbalance calibration circuit. The RS1007RF integrates a low pass filter with DC offset calibration, mixer (upconverter), VGA, Delta Sigma fractional N PLL, VCO and RC auto calibration circuit. It is highly integrated with low power consumption and a high price/performance ratio. Both chips are available in a 5x5mm QFN28 package.

"Jazz Semiconductor's 0.18um SiGe BiCMOS technology offers many advantages including accurate modeling, low cost, and good technical support. The Jazz process design kit (PDK) has extensive models covering analog, mixed signal and digital components to optimize our product designs. Using Jazz allowed us to accelerate our time to market and improves the overall quality of our design," said Mr. Zheng Weiguo, chief engineer of Rising. "We are very satisfied with Jazz's 0.18um SiGe BiCMOS technology and plan to continue our partnership to design other subsequent projects in other target markets, including TD-SCDMA, multiband GSM, 802.1x wireless broadband and high speed optical communications."

"Our collaboration with Rising is an example of Jazz's dedication to our customers' success in RF design," said Dr. Theodore Zhu, chief marketing officer and vice president of sales at Jazz Semiconductor. "We continue to provide optimized processes, superior design infrastructure and support to our customers to enable their innovative products. We look forward to maintaining our relationship with Rising as they continue to design their next generation products."
