Antennas RF Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer documentation may contain updated mechanical tolerances or testing conditions. Confirm that the adhesive mounting style aligns with your assembly process requirements. Ensure the receiving facility handles ESD-sensitive components appropriately during storage and installation.

Antennas RF Selection Notes

Select this model when a low-profile solution is required for 868/915 MHz operations. The -2.7 dBi gain is typical for embedded chip antennas; ensure system link budgets account for this loss. Compare against ACAJ-109-T if cellular bands are needed instead of ISM frequencies. Verify ground plane clearance requirements on the host PCB to maintain the specified 3:1 VSWR performance.
