Antennas RF Procurement Notes

Verify the ordering suffix 'T' indicates vacuum-sealed tray packaging containing 50 units per tray. Confirm that the procurement quantity aligns with suggested batch sizes, such as 1000 pieces comprising 20 trays. Ensure compatibility with standard surface-mount assembly processes before finalizing purchase orders.

Antennas RF Selection Notes

Select this component when a 18mm x 18mm footprint is required for GPS integration. Consider the 3.3 dBi gain and 6 MHz bandwidth specifications against system link budget requirements. Evaluate the 4.0 mm height constraint relative to enclosure design limitations. Verify RHCP requirements match the receiving antenna characteristics.

Antennas RF Part Context

This part belongs to the APAE series of GPS patch antennas from Abracon. It shares the 1.57542 GHz operating frequency with other models in the family but differs in physical dimensions and gain. Similar parts include the APAE1575R1540AZDB2F-T and APAE1575R1240ABDD1-T, which offer smaller footprints.

Antennas RF Replacement Considerations

Direct substitutes include the APAE1575R1840AADB7-T, which shares identical dimensions and frequency specifications. Cross-reference mechanical drawings and mounting hole patterns to ensure compatibility. Verify that alternative components meet the same RHCP and impedance requirements.
