Antennas RF Procurement Notes

Verify the specific pin configuration and LNA voltage requirements against the official datasheet before integration. Confirm that the operating frequency range aligns with the target GNSS constellations. Ensure mechanical dimensions fit the designated PCB area. Check RoHS compliance status if required by project specifications.

Antennas RF Selection Notes

Select this model when high-accuracy GNSS performance is required in a compact surface-mount form factor. The integrated LNA supports weak signal environments. Compare VSWR and gain metrics against alternative ceramic patch antennas to ensure compatibility with existing RF front-end designs and impedance matching networks.
