Antennas RF Procurement Notes

Verify component availability status prior to procurement, as this part number may be subject to discontinuation or end-of-life restrictions. Confirm that the specified surface mount solder termination aligns with the target PCB assembly process capabilities. Ensure that the operating frequency range matches the system requirements for the intended ISM application environment.

Antennas RF Selection Notes

Select this component when a low-profile surface mount solution is required for sub-GHz ISM frequencies. Consider the -8.7dBi gain specification relative to system link budget requirements. Evaluate the physical dimensions and solder termination type against available board space and manufacturing constraints compared to through-hole alternatives.

Antennas RF Part Context

This antenna belongs to the microSplatch series of chip antennas from TE Connectivity Linx. These components are engineered for high efficiency in small footprints, supporting various wireless protocols including Bluetooth, Wi-Fi, and Zigbee across different frequency bands. The specific model targets the 400MHz segment of the UHF spectrum.

Antennas RF Replacement Considerations

The ANT-403-USP has been discontinued. Public confirmed substitute part numbers include ANT-433-USP-T and ANT-433-USP410. Verify frequency compatibility and gain specifications when transitioning to these alternatives.
