SAM-M8Q - Easy-to-use u-blox M8 GNSS antenna module

Smart antenna module for easy and reliable GNSS integration.

SAM-M8Q is the u-blox GNSS patch antenna module that is ideal for easy and reliable GNSS integration. With the exceptional performance of the u-blox M8 concurrent GNSS (GPS, GLONASS, Galileo, QZSS and SBAS) engine, the SAM-M8Q delivers high sensitivity and minimal acquisition times in an ultra compact form factor.

Incorporating the SAM-M8Q module into customer designs is simple and straightforward, thanks to the embedded GNSS patch antenna, low power consumption, simple interface, and sophisticated interference suppression that ensures maximum performance even in GNSS-hostile environments.

The 15 x 15 mm patch antenna provides the best compromise between the performance of a Right Hand Circular Polarized (RHCP) antenna and a small size to be integrated in any design. The omni-directional radiation pattern increases flexibility for device installation. SAM-M8Q's robustness, easy design-in, surface embedded antenna, and easy interfacing ensure faster time to market and keep design and manufacturing costs to a minimum.

The SAM-M8Q module features an additional front-end LNA for optimized performance and a front-end SAW filter for increased jamming immunity.

The SAM-M8Q module targets industrial and consumer applications that require small, cost efficient, and ready-to-use GNSS solutions. SAM-M8Q is based on the u-blox M8 FW3 engine with cutting-edge performance and additional features not available on any other antenna modules in the market. It also provides message integrity protection, geofencing, spoofing detection, and odometer functionalities.

Key features:

  • Easy to design‑in with no RF expertise required
  • Consistently strong performance regardless of installation
  • High accuracy thanks to concurrent reception of up to 3 GNSS (GPS, Galileo, GLONASS)
  • Tiny form factor 15.5 x 15.5 x 6.3 mm
  • Embedded wide‑band patch antenna
  • Surface‑mount device, enabling simple and automated manufacturing
