Antennas RF Procurement Notes

Verify that the specific part number suffix 'X' indicates a unit requiring customer-side PCB tuning before final assignment of a fixed letter designation. Confirm compatibility with the target application's frequency requirements within the 1.575 GHz to 1.602 GHz range. Ensure the procurement process accounts for the necessary post-purchase calibration steps defined by the manufacturer for this specific variant.

Antennas RF Selection Notes

Select this component when a compact ceramic patch antenna is required for dual-band GPS and GLONASS support. The 50Ω impedance ensures standard RF interface compatibility. Consider the requirement for custom PCB tuning associated with the 'X' suffix during the design phase. This model is appropriate for applications prioritizing space-constrained SMD implementations over higher gain alternatives.
