Communication Module Compatible with ELTRES™

The CXM150xGR series has been commercialized as a communication module fully compliant with the ELTRES communication standard. The small 16 x 16 mm module size (16×24mm for CXM1502GR) optimizes all functionality and high-frequency circuitry required for ELTRES communications, allowing IoT terminals to be configured with minimal number of external components and simple control.

Key Features:

  • Built-in π/2-shift BPSK modulation (two-phase skew modulation) LSI with low power consumption and good signal-to-noise ratio for narrowband communications.
  • Built-in impedance matching circuit with external Sub-GHz band antenna enables direct connection when using a general-purpose antenna (easy antenna design when using a dedicated antenna).
  • Built-in GNSS reception LSI with high sensitivity and low power consumption compatible with GPS/GLONASS/QZSS (Michibiki)
  • Optimized high frequency circuitry for GNSS reception is built in, enabling direct connection of an external GNSS antenna.
  • Stand-alone capability for automatic payload generation and autonomous wake-up/deep sleep operation for easy external control.
  • Compliant with relevant radio standards in each country/region.
