ANT1025

Antennas RF Overview

The ANT1025 is a dual-band ceramic patch antenna manufactured by RFMi, designed for global navigation satellite systems. It operates at center frequencies of 1.575 GHz and 1.602 GHz, supporting GPS and GLONASS signals. The component utilizes a surface-mount package with adhesive mounting options, ensuring secure attachment to device substrates. Its compact form factor makes it suitable for integration into portable electronic devices requiring precise location tracking capabilities.

Antennas RF Feature Summary

• Dual-band operation supporting both GPS and GLONASS frequency bands
• Ceramic patch construction for durability and signal stability
• Surface-mount design with adhesive mounting capability

Antennas RF Applications

• GPS navigation modules in consumer electronics
• GLONASS positioning systems in automotive devices
• Portable location tracking hardware

Antennas RF Procurement Notes

Verify the specific suffix variant (e.g., -DG) against the required mounting style and lead-free compliance status. Confirm that the adhesive backing specification matches the target assembly process requirements. Ensure the operating temperature range aligns with the final product's environmental conditions before placing orders.

Antennas RF Selection Notes

Select this component when dual-frequency GNSS support is required within a constrained footprint. The ceramic material offers consistent performance across varying environmental conditions compared to some polymer alternatives. Consider the adhesive mounting method if through-hole or standard solder-only reflow processes are not feasible for the specific PCB layout constraints.

Antennas RF Part Context

RFMi specializes in radio frequency components using SAW, crystal, and ceramic technologies. The ANT1025 belongs to their navigation antenna family, distinct from their resonators and transmitters. This part addresses the growing demand for integrated GNSS solutions in compact wireless devices without requiring external bulky antennas.

Antennas RF Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing RF front-end designs if considering alternative manufacturers.
