2461

Overview

The Adafruit Industries LLC part number 2461 is a passive ceramic patch antenna designed for RF applications. It operates at a center frequency of 1.575 GHz, which corresponds to the GPS L1 band. The component features a uFL connector interface and has physical dimensions of 15mm by 15mm. It provides a gain of 1 dBi. The antenna is classified under RF antennas and is intended for integration into wireless systems requiring precise positioning capabilities.

Feature Summary

• Passive ceramic construction for durability
• Optimized for GPS L1 band reception
• Compact surface-mount form factor

Applications

• GPS module integration
• Navigation device development
• IoT location tracking hardware

Procurement Notes

Verify the specific connector type required for your PCB layout, as this model utilizes a uFL interface. Confirm that the operating frequency aligns with your system's design requirements before procurement. Ensure mechanical clearance matches the 15mm x 15mm footprint constraints in your enclosure design.

Selection Notes

Select this component when a low-profile, passive solution is needed for GPS signal acquisition. Consider the uFL connector compatibility with your existing RF chain. Evaluate the 1 dBi gain against system link budget requirements to ensure adequate signal strength for the intended application environment.

Part Context

This antenna belongs to the category of RF antennas and specifically falls under the sub-category of passive GPS antennas. It is distinct from active antennas or those with different connector types like SMA. The product serves as a critical interface between the RF front-end and satellite signals.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative antennas based on frequency, gain, and connector specifications.
