Antennas RF Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct configuration. Confirm that the received components match the specified RoHS compliance status and moisture sensitivity level (MSL 1). Cross-reference the part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Antennas RF Selection Notes

Select this component when a single-band GNSS solution is required for compact embedded designs. The 0402 metric footprint suits high-density PCB layouts. Ensure the host circuitry supports the 50 Ohm impedance matching network. Consider thermal stability requirements as the operating range extends from -40°C to +85°C.

Antennas RF Part Context

This part belongs to the ANT161575 series of LTCC antennas from TDK. It is distinct from multi-band variants like the ANT161575TT-3000A1, which supports additional WLAN and Bluetooth frequencies. The ST-1202A1 designation specifically identifies the single-band GNSS configuration within the product family.

Antennas RF Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify mechanical compatibility and electrical performance with alternative TDK series parts if sourcing constraints exist.
