• Right-hand circular polarization for optimal signal reception
• Ceramic housing suitable for high-temperature industrial environments

Antennas RF Applications

• Navigation devices requiring precise positioning
• Telematics boxes for vehicle tracking
• Fleet management systems

Antennas RF Procurement Notes

Verify that the specific part number corresponds to the passive antenna variant rather than the active version, as the product line includes models with integrated LNAs. Confirm mechanical dimensions and mounting requirements against the official datasheet to ensure compatibility with the target PCB layout. Check RoHS compliance status if required by project specifications.

Antennas RF Selection Notes

Select this component when a passive solution is preferred over active antennas to reduce system power consumption. Ensure the application environment falls within the specified operating temperature range of -40°C to +105°C. Verify that the 50 Ohm impedance matches the RF front-end interface and that the physical footprint fits the available board space.

Antennas RF Part Context

This model belongs to the ANT2525 series of GNSS antennas from Pulse Electronics. The series includes various configurations such as the ANT2525B00DT1516S passive patch and the ANT2525JB12BGNSSA active variants. These components are engineered for compact embedded applications where size constraints and signal integrity are critical for global navigation satellite system performance.

Antennas RF Replacement Considerations

The ANT2525B00DT1516S is a comparable passive patch antenna within the same family. When substituting, verify that the replacement maintains identical frequency coverage, polarization, and mechanical dimensions to ensure seamless integration without redesigning the host circuit board.
