RFaxis to Unveil Roadmap for Unified 2G/3G/4G CMOS Transmit IC at the 2011 Mobile World Congress

RFaxis Pure CMOS Multi-Mode/Multi-Band Transmit ICs Dramatically Simplify RF Front-End Designs of Smartphones and Mobile Internet Devices for GSM/GPRS/EDGE/WCDMA/LTE

IRVINE, CA--(Marketwire - February 9, 2011) - RFaxis, a fabless semiconductor company focused on innovative, next-generation RF solutions for the wireless connectivity and mobility markets, today announced plans to unveil its roadmap for its portfolio of pure CMOS cellular mobile device transmit ICs at the 2011 Mobile World Congress in Barcelona, Spain. This roadmap will include a new series of CMOS-based GSM/GPRS-capable transmit ICs as well as unified RF Front-end transmit solutions to significantly simplify cellular mobile device designs for all major existing and anticipated cellular standards including GSM/GPRS/EDGE, WCDMA/HSPA+, CDMA200/EVDO and LTE. 

To support ubiquitous voice and data connections anywhere in the world for popular cellular mobile devices such as smartphones and tablets/MIDs (Mobile Internet Devices), the RF industry has implemented RF Front-end components that enable seamless transmit and receive of wireless signals based on 2G (GSM/GPRS/EDGE), 3G (WCDMA/HSPA/CDMA2000/EVDO) and upcoming 4G (LTE) standards, and at different region or carrier-specific frequency bands. Unfortunately, these conventional RF Front-end components, especially the critical power amplifiers, are very complicated, inefficient and costly. In fact, these conventional RF Front-end components are mostly designed using expensive gallium arsenide (GaAs), and must be combined with CMOS-based control circuitry to meet the stringent RF performance and talk-time requirements from leading cellular device manufacturers. RFaxis' new Mobility Business Unit builds upon their successful commercialization of its portfolio of the world's first silicon-based single-chip/single-die RF Front-end ICs (RFeIC™) for wireless connectivity applications, and has innovated revolutionary RF solutions in CMOS to address the challenges of the rapidly evolving multi-mode/multi-band cellular mobile device market. 

The foundation for the RFaxis Mobility roadmap is the patent-pending RF Mobility architecture platform. This roadmap begins with a family of CMOS transmit ICs comprised of linear power amplifiers optimized for best-of-class DG.09 current consumption as well as stringent EDGE/WCDMA/LTE linearity requirements. Next on the roadmap are the new RFaxis RFM8006 low-band and RFM007 high-band CMOS transmit ICs that support both nonlinear GSM/GPRS and linear EDGE/WCDMA/LTE operations. The RFM8006 is designed to operate over the frequency range from 698 through 915MHz, which includes the 3GPP FDD Bands 5, 6, 8, 12-14 and 17-20. The complementary RFM8007 is designed for the higher frequency range from 1710 through 1980MHz, thereby covering the 3GPP the FDD Bands 1, 2, 3, 4, 9 and 10. Following closely behind these ICs is the new RFaxis RFM8010 unified CMOS broadband transmit IC that will efficiently amplify transmit signals substantially for all operation modes (2G/2.5G/3G/3.5G/4G) and all frequency bands (700-2100MHz) as required by both existing and next-generation cellular mobile devices.

"The cellular mobile device market is rapidly moving towards 3G/4G standards in order to support bandwidth-intensive data applications such as real-time video," commented Dr. Oleksandr Gorbachov, CTO of RFaxis. "Meanwhile these devices still need to be backward compatible with 2G/2.5G modes including GSM, GPRS and EDGE. At RFaxis, we have proven that RF Front-end circuits with excellent power-added efficiency and DG.09 current for linear power amplification can be realized using standard CMOS processes via our innovative architecture and clever circuit design techniques. After extensive design iterations, we are now successfully employing our special design techniques for saturated GSM/GPRS power amplification using the same standard CMOS processes. By combining our power amplification circuits with a properly designed DC-DC converter, we have enabled our RFM8010 to be a universal multi-mode/multi-band pure CMOS transmit IC that supports virtually any mode and any frequency band as required by our customers."

"We are excited about how our Mobility game plan will help the cellular mobile ecosystem take a huge leap forward," said Mike Neshat, chairman and CEO of RFaxis. "Today, popular cellular mobile devices such as smartphones and tablets are highly integrated and boast a very long list of popular features. However, the critical component in these devices that has the highest impact on battery life remains the RF transmit circuit, and this component still has much room for improvement in terms of performance and cost. For example, a typical multi-mode/multi-band smartphone today may contain from three to five power amplifier modules to support voice and data operations. Not only does this conventional topology take away precious board space, it makes system design more complex and costly, and may drain the device's battery faster than needed. Consistent with the overall RFaxis mission, our Mobility objective is to reduce the RF design complexity, and therefore time-to-market for these devices by providing a common platform design for various multi-band combinations, yet still delivering high-efficiency, easy-to-integrate, best-cost single placement transmit ICs. By reclaiming circuit board real estate and battery current, designers have the freedom to make their cellular mobile devices more compact and convenient, last longer between battery charges or add more user-demanded features."
