Antennas RF Procurement Notes

Verify the specific suffix DT1516S against official datasheets to confirm mechanical dimensions and termination style. Ensure compatibility with PCB footprint requirements and soldering profiles. Confirm environmental ratings such as operating temperature range (-40 C to +105 C) match application constraints. Cross-reference ECCN classification for export compliance if necessary.

Antennas RF Selection Notes

Select this model when integrating GPS and GLONASS capabilities into compact electronic assemblies requiring surface-mount technology. The 50 Ohm impedance ensures standard RF interface matching. Consider the 4 mm height profile for clearance constraints. Verify that the 20 MHz bandwidth adequately covers the required satellite constellation signals for the target region.
