Antennas RF Procurement Notes
Verify current lifecycle status as sources indicate this part may be Not Recommended for New Design (NRND). Confirm availability through authorized distributors. Ensure compatibility with existing PCB layouts regarding the 35x35mm footprint and 4mm height constraints. Validate that the pin connector interface matches the host board design requirements.
Antennas RF Selection Notes
Select this model for applications requiring a low-profile, multi-band GNSS solution. The ceramic patch technology provides durability in harsh environments. Consider the NRND status when planning long-term production cycles. The 4.5 dBi gain is adequate for standard indoor and outdoor positioning tasks where space is limited.
Antennas RF Part Context
This component belongs to Quectel's embedded antenna portfolio, focusing on GNSS connectivity. It complements cellular modules by providing precise location data. The design prioritizes minimal profile and robust signal reception across major global satellite constellations.
Antennas RF Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the Not Recommended for New Design (NRND) status, alternative components should be evaluated based on identical electrical specifications and mechanical dimensions.
