Antennas RF Procurement Notes

Verify the specific datasheet version to confirm mechanical dimensions and impedance matching requirements for your PCB layout or cable assembly. Ensure the SMA connector polarity matches your system design. Confirm RoHS compliance status if required by your manufacturing standards. Check lead times as this item may be non-stocked depending on regional distribution channels.

Antennas RF Selection Notes

Select this model when a low-profile helical antenna is required for sub-GHz cellular bands. The negative gain value indicates it is suitable for close-proximity applications where space is limited rather than long-range directional needs. Verify that the 5-watt power rating aligns with your transmitter output capabilities to prevent damage.

Antennas RF Part Context

This part belongs to the ANT-450 series from TE Connectivity Linx, focusing on UHF cellular frequencies. It complements other antennas in the PW and HW series, offering a balance between size and performance for IoT deployments. The helical structure distinguishes it from standard whip antennas by providing a more compact form factor while maintaining adequate radiation efficiency.

Antennas RF Replacement Considerations

Direct substitutes include ANT-450-PW-LPN for similar helical characteristics but different mounting styles. For whip-style alternatives, consider models within the same CW-HW series. Always verify connector type and frequency range compatibility before swapping components.
