SiGe’s SE4120S the world’s smallest GNSS receiver, wins Electronic Products China
March, 2008—Beijing, China
SiGe Semiconductor, Inc. has been presented with a prestigious Product Award, for its SE4120S, by Electronic Product China (EPC) magazine. SiGe’s SE4120S is the world’s smallest Global Navigation Satellite System (GNSS) receiver IC for mobile handsets, cellular telephones, personal navigation devices (PNDs) and personal digital assistants (PDAs)
EPC is one of China’s most authoritative electronics industry trade publications. EPC’s judging panel of industry experts deliberated over a diverse range of leading manufacturers’ products. Winning products were chosen based on how well they met a number of criteria including: design innovation, price performance and technology advancement.
“The team at SiGe is always very proud when one of our products is recognized in this way. With the award winning SE4120S, integrating navigation capability into mobile handsets has never been easier. Our customers can easily meet shrinking form factor requirements of consumer electronics while packing in all of the performance, feature integration and battery efficiency desired by end users,” said Alistair Manley, vice president of marketing at SiGe Semiconductor. The SE4120S is based on SiGe’s SE4120L, a GNSS receiver with built-in support for software-defined satellite signal processing for both GPS and Galileo. 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. Under controlled conditions, systems using the SE4120S are capable of tracking satellite signals down to as low as -170 dBm. The device also uses a 3-wire IF connection bus, with near-zero IF and serialized data output, allowing non-proprietary general-purpose microprocessors running software-define signal processing to interface to the device in a simple manner. Software approaches allow the correlation and navigation functions to be efficiently performed by using the existing processing power available in the application microprocessor of consumer electronic devices. This increases scalability, offering greater GPS/Galileo performance, while also allowing customers to support increased feature integration.
The SE4120S particularly addresses the issue of size in the convergence of technology integration in mobile devices and is key to the integration of navigation with Bluetooth and WLAN. These devices take advantage of chip-scale package technology to enable complete receiver solutions that measure just 2.2 x 2.2 x 0.4mm. This is 70% smaller than the existing 24-lead QFN-packaged versions of these devices, and 70% smaller than competitive receivers on the market, making them ideal for mobile handsets and other small form factor consumer devices.
“SiGe would like to thank EPC for acknowledging the innovative design, performance gains, and significant technology advancements that we have achieved while maintaining cost effective pricing with the development of the SE4120S. This EPC Product Award encourages us to maintain our efforts in delivering innovative RF front-end solutions for next-generation wireless systems to our valued clients,” said Manley”.
