The SE4150L was specifically 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 4x4 mm package, it features a multi-bit output, which improves sensitivity and interference resistance for GPS solutions. This new GPS receiver offers a system noise figure of 1.0 dB and input third-order intercept performance (IIP3) of better than 0 dBm. The SE4150L builds on the successes of SiGe Semiconductor’s award-winning SE4120L and SE4110L, and offers additional features to facilitate the implementation of an internal or external antenna architecture.
It operates over a supply range of 2.7 to 3.6 V and features a low standby current of <10µA. The device's digital I/Os and supplies have all been designed to operate from 1.6 to 3.6 V to interface with smaller geometry baseband ICs and SoCs.
The receiver simplifies dual-antenna system design because it integrates antenna sensing, switching, and a high-performance low noise amplifier (LNA). It also automatically responds to the connection of an external antenna and interfaces directly to the GPS baseband processor to provide a complete GPS radio receiver system.
