Multi-Constellation, Single-Frequency (L1) Positioning GNSS

The SE868K5-SF is a multiconstellation positioning receiver module and last member of the xE868 family. Its compact size, excellent power consumption, strong immunity to interference, and oprimized L1 position engine offer an ideal solution for multiple use cases and applications.
It embeds and internal LNA, SAW, and supports the following:

  • GPS/QZSS in the L1 band
  • Galileo in the E1 band
  • GLONASS in the L1 band
  • BeiDou in the B1 band
  • Satellite-based augmentation systems (SBAS) in the L1 band

Product Description

The SE868K5-D is a multi-constellation positioning receiver module and a member of the xE868 Telit Cinterion form factor family. With is extremely low power consumption, it is ideal for battery powered applications and, thanks to its SAW filter, offers optimal performances even in radio noisy environments or in case of co-location with other technologies. This module can navigate down to -165 dBm and, with its internal LNA, proved optimal performance even in harsh environments.

Form Factor Family

The SE868 sub-compact form factor is a well established industry standard in a 11 x 11mm, 32-pad QFN-like package. Models in the family vary in depth dimension from 2.6 to 6.1 mm depending on presence and type of integrated antenna.
