Description

The R4 Series GPS receiver module is a self-contained high-performance

GPS receiver with an on-board LNA and SAW filter. Based on the SiRFstar

IV 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 R4 Series receiver can acquire and track up to 48 satellites

simultaneously in just seconds, even at the lowest signal levels. These

features, along with the module’s standard NMEA data output, make it

easy to integrate, even by engineers without previous RF or GPS

experience. The Linx R4 Series GPS modules offer a simple, efficient and

cost-effective method of adding GPS capabilities to any product.

The evaluation module contains the surface mount R4 Series GPS module,

SMA connector and a ferrite bead (used to supply power to an external

active antenna, such as the Linx SH Series active GPS antenna) on a single

board with through-hole headers. This small board makes prototyping with

the R4 Series module very easy.
