Antennas RF Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as distributors may list variations such as tape-and-reel or cut-tape formats. Confirm that the component meets the required environmental certifications, specifically RoHS3 compliance, for your target market regulations. Cross-reference the manufacturer part number with distributor codes to avoid selection errors during procurement.

Antennas RF Selection Notes

Select this antenna when a compact solution is required for 870 MHz ISM applications. Ensure the design accommodates the 1608 metric footprint and the 1.20 mm maximum height constraint. Verify that the system impedance matches the 50 Ohm specification to maintain optimal signal transfer and minimize reflection losses in the circuit layout.

Antennas RF Part Context

This component belongs to the ANT1204 series from Pulse Electronics, which focuses on embedded ceramic antennas for wireless connectivity. The series supports various frequencies within the UHF range, allowing designers to choose specific models based on regional ISM allocations. This particular variant targets the 870 MHz segment, offering a balance between size and performance for space-constrained electronic devices.

Antennas RF Replacement Considerations

The ANT1204LL08R0870A is a related model within the same series operating at the same frequency. Designers should verify if differences in physical dimensions or specific electrical tolerances between these variants impact the mechanical fit or RF performance requirements of the assembly.
