White Paper

The u‑blox CAM‑M8Q chip antenna module has the exceptional performance of the u‑blox M8 multi-GNSS (GPS/QZSS, GLONASS and BeiDou) engine in an industry proven form factor. The CAM‑M8Q offers high sensitivity and strong signal levels in an ultra compact form factor. Incorporating the CAM‑M8Q into customer designs is simple and straightforward, thanks to the embedded GNSS antenna, small footprint of 9.6 x 14 x 1.95 mm, and sophisticated interference suppression that ensures maximum performance even in GNSS-hostile environments. The low power consumption and thin design allow end devices to be slimmer and smaller. Despite of miniature size, the chip antenna in the CAM‑M8Q performs extremely well against traditional patch antennas. Optimal performance is achieved by following design instructions available in the Hardware Integration Manual as customer PCB is part of the antenna solution.The omnidirectional radiation pattern increases flexibility for device installation. Optionally, CAM‑M8Q can be connected to an external GNSS antenna. The SMD design keeps manufacturing costs to a minimum and the small mass ensures high reliability. The CAM‑M8Q targets industrial and consumer applications that require concurrent GPS and GLONASS or BeiDou reception. The CAM‑M8Q is form-factor compatible to UC530 and UC530M modules, allowing the upgrade of existing designs with minimal effort. CAM‑M8Q modules use GNSS chips qualified according to AEC-Q100 and are manufactured in ISO/TS 16949 certified sites. Qualification tests are performed as stipulated in the ISO16750 standard: “Road vehicles – Environmental conditions and testing for electrical and electronic equipment”. CAM‑M8Q complies with green / halogen-free standards.
