The SE868K3-A/AL Series from Telit are Multi-Constellation GNSS Patch Antenna Modules that operate in the GPS L1, GLONASS L1, QZSS L1, and Galileo L1 bands. These smart antenna modules provide a sensitivity of up to -145 dBm during data acquisition and -160 dBm during tracking. The module consists of a low-profile SMT Patch Antenna, SAW filter, flash memory, multi-constellation GNSS core, RTC, and TCXO. These antenna modules require a DC supply from 3 to 4.3 V and consume less than 100 mW of current in full-power acquisition mode, and less than 30 µW of power in backup mode. They combine the advanced features and a low-profile design to significantly simplify the integration process for space-constrained applications by eliminating the need for external components.
The SE868K3-A/AL modules are capable of tracking GPS + GLONASS and Galileo constellations simultaneously and providing the positioning data though standard UART, I2C, or SPI interfaces. They are available in a surface-mount 32-pad QFN package that measures 11 x 11 x 6.1 mm.
