  • Very Low Power
  • Very Small Form Factor

GPS Receiver+ Patch Antenna for All Kind of Applications

SLS-1548 GPS Smart Antenna is the all-in-one solution when you need to combine GPS receiver and antenna together in a small but high performance device. Market leading cold start sensitivity of -157 dBm makes it possible to acquire satellite signals and start navigating in places where competing devices do not get even the first fix.
Our receiver is suited for tracking devices with covert installations (weak signal environment) and battery operated consumer products like personal navigation devices, handheld computers, vehicle locators. All in a very small foot print.

Highest Performance, Simple Design

SLS-1548 has a market leading navigation sensitivity of -161 dBm. This makes it possible to continue navigation in extremely difficult environments, such as indoors, urban canyons or deep foliage. On board back-up battery allows to simplify design of portable devices. On board MCX connector allow to use external antenna.

Lowest Power Consumption

SLS-1548 has internal high-efficiency circuitry which provides market lowest power consumption in tracking mode. During tracking mode max current is 30 mA. When operated in idle mode battery consumption goes down to few uA. During tracking mode maximum current consumption is 30 mA.


SiGe RF Circuit provides superior ESD protection and robustness to meet the severe requirements of both Automotive and Industrial markets

Operating Temperature Range

SLS-1548 is built to perform in the -40 +85 degree Celsius temperature range.
