Antennas RF Procurement Notes

Verify the specific datasheet version and manufacturing date code prior to procurement, as component specifications may evolve. Confirm that the selected antenna variant matches the required frequency bands and impedance characteristics for the target application. Ensure compliance with local regulatory requirements regarding RF emissions and safety standards before finalizing the supply chain agreement.

Antennas RF Selection Notes

Select the YC0001AA when a low-profile, dual-band LTE solution is required for SMD assembly. Consider its 35x8.5mm footprint and 3mm height against available board space. Evaluate the 3dBi gain and VSWR performance relative to the device's enclosure materials and placement constraints to ensure adequate signal integrity without requiring external amplification.
