SiGe Semiconductor Inc. rolls out a radio receiver featuring dual-antenna input capability for next-generation GPS systems.

The SE4150L GPS radio receiver was designed to address the three primary challenges associated with embedded GPS applications: small size, low power and low price, all while raising the bar for performance. Housed in a low profile 4mm x 4mm package, the SE4150L features a multi-bit output, which improves sensitivity and interference resistance for GPS solutions. The GPS receiver offers a system noise figure of 1dB and input third-order intercept performance (IIP3) of better than 0dBm.

The SE4150L is based on SiGe Semiconductor's SE4120L and SE4110L, and offers additional features to facilitate the implementation of an internal or external antenna architecture. The SE4150L operates over a supply range of 2.7-3.6V and features a low standby current of <10µA. The device's digital I/Os and supplies have all been designed to operate from 1.6V to 3.6V to interface with smaller geometry base band ICs and SoCs. The SE4150L GPS receiver integrates antenna sensing, switching, and a high-performance low noise amplifier, simplifying dual-antenna system design.

Pricing is less than Rs.60.03 ($1.50) in 10,000 quantities. Devices are sampling now to lead customers and will be widely available for sampling in July.
