Antennas RF Procurement Notes

Verify the specific datasheet version W712 or current equivalent from Pulse Electronics before procurement. Confirm that the 315 MHz frequency aligns with regional regulatory requirements for your target market. Ensure the PCB layout matches the recommended footprint for the 12.00x4.00x1.50 mm package to maintain performance integrity.

Antennas RF Selection Notes

Select this model when a compact, low-profile antenna is required for 315 MHz operations. The SMD form factor facilitates automated assembly via tape and reel packaging. Consider the 1.50 mm height constraint for tight enclosure designs. Verify impedance matching requirements against the transceiver module to ensure optimal signal transmission efficiency.

Antennas RF Part Context

This component belongs to the 1204 series of chip antennas from Pulse Electronics. The series offers various frequency options tailored for different ISM bands. The ANT1204LL20R0315A specifically addresses the 315 MHz segment, providing a standardized solution for manufacturers needing reliable internal antenna integration without external protrusions.

Antennas RF Replacement Considerations

Consult official Pulse Electronics documentation for direct substitutes within the 1204 series. Alternative frequencies such as 433 MHz or 900/1800 MHz variants exist but require frequency verification. No generic cross-model replacements are confirmed without explicit manufacturer validation.
