SiGe Semiconductor’s SE4120L Galileo-ready receiver wins industry innovation award
November, 2007—Hong Kong
SiGe Semiconductor’s SE4120L, the world’s first Galileo-ready receiver IC, has received a leading product accolade in the prestigious EDN (Electronic Design News) China Innovation Awards 2007. The SE4120L was successful in the highly competitive Communications and Network IC category. The receiver with built-in support for software-defined satellite signal processing for both GPS and Galileo enables high accuracy navigation services in portable devices, including laptop computers, PDAs, media players, cell phones, and cameras.
Galileo is a new satellite system that will greatly enhance navigation and positioning performance compared with the existing GPS system. The combination of GPS and Galileo will improve user experience of location-based services by enabling products to determine position data much more consistently, more quickly, and with greater accuracy than with GPS alone.
Commenting on winning the award, Peter Gammel, chief technical officer and vice president engineering at SiGe Semiconductor, said, “We are delighted to receive this prestigious industry recognition from EDN China for the SE4120L. We are the only semiconductor supplier able to meet the needs of OEMs wishing to deliver GPS solutions and provision for the emerging Galileo market. Our unique software-defined signal processing architecture allows manufacturers to design with a single solution that can be upgraded via software as developing GPS systems are established. It is satisfying to know that EDN China’s knowledgeable design engineer readers have quickly realized that the SE4120 allows them to capitalize on the global satellite navigation market - expected to reach US $30 billion by 2008.”
Products were assessed and selected by a panel of EDN China judges, consisting of industry experts and specialists from China’s leading OEM companies, academic institutes, universities and EDN China’s editorial board. Readers and registered users of EDN China were invited to vote for the winners in nine categories.
SE4120L’s software architecture greatly reduces the load on host processors compared with conventional software approaches, and reduces cost and power consumption compared with dedicated hardware.
The device features high integration to reduce the system bill of materials and overall cost. The integrated architecture includes an on-chip high-gain LNA capable of delivering 18dB of gain at a low noise figure of 1.6 dB without the need for bulky active antennas and costly, power-hungry external amplification. Eliminating these components reduces BOM cost and power consumption by over 50 percent while minimizing board area and maintaining high overall performance. The SE4120L is optimized for the lower possible power consumption, operating at less than 10 mA from a 2.7-3.3 V supply. Under controlled conditions, systems using the SE4120L are capable of tracking satellite signals down to as low as -170 dBm.
The receiver also includes a linear AGC and a multi-bit analog to digital converter (ADC) with low digital IF. The device sampling is software-configurable and includes support for low bandwidth serialized multi-bit I/Q output. A PLL synthesizer and image reject mixer further reduce external component count to simplify integration. The IF filters are programmable in software to support GPS and Galileo simultaneously or GPS operation alone.
Peter Gammel concluded, “Everyone at SiGe appreciates receiving this industry honor. As the satellite navigation market matures, we look forward to a bright future for the award-winning SE4120L receiver.”
