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

According to the press release, RS1007W and RS1007RF offer a complete solution for the RF front-end chipset for 3G WCDMA wireless handsets. 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. 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 0.18m SiGe BiCMOS technology offers many advantages including accurate modeling, low cost, and good technical support," 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."
