Antennas RF Procurement Notes

Verify the specific suffix TL1 against the manufacturer's current datasheet to confirm package dimensions and soldering profile requirements. Ensure the procurement channel provides original TE Connectivity or Laird documentation. Cross-reference the part number with official RoHS compliance statements if environmental regulations apply to the target assembly. Confirm that the received components match the specified L1 band performance characteristics before integration into final products.

Antennas RF Selection Notes

Select this component when designing GPS-enabled devices requiring a low-profile surface mount solution. Evaluate the antenna's gain and bandwidth specifications against the system's sensitivity requirements. Consider the physical footprint constraints of the PCB layout during the selection process. Ensure the operating temperature range aligns with the intended environmental conditions of the end application. Verify compatibility with the specific RF front-end architecture of the target receiver module.
