SR and SG Series GPS Modules



GPS receivers from Linx Technologies are compact, robust, and cost effective

SR and SG Series GPS Modules The SR series GPS receiver module from Linx Technologies is a self-contained high-performance GPS receiver with an onboard antenna, LNA, and SAW filter. Based on the SiRFstar III chipset, it provides exceptional sensitivity, even in dense foliage and urban canyons. The module’s very low power consumption helps maximize runtimes in battery-powered applications. With over 200,000 effective correlators, the SR series receiver can acquire and track up to 20 satellites simultaneously in just seconds, even at the lowest signal levels. Housed in a compact reflow-compatible SMD package, the receiver requires no programming or additional RF components to form a complete GPS solution. These features, along with the module’s standard NMEA data output, make the SR series easy to integrate, even by engineers without previous RF or GPS experience.

The Linx SG series embeddable GPS module provides a complete high-performance GPS receiver solution in a compact (13x15mm), reflow-compatible SMD package. It utilizes the SiRFstar III low-power chipset that minimizes power consumption and provides exceptional sensitivity, even in dense foliage and urban canyons. The receiver features an onboard LNA and SAW filter and requires no additional RF components (except an antenna). Programming is not required, and the module’s standard NMEA data output makes the series easy to integrate, even by engineers without previous RF or GPS experience.
