AFS14A04-1575.42-T2

Overview

The AFS14A04-1575.42-T2 is a Surface Acoustic Wave (SAW) filter manufactured by Abracon LLC, designed for general-purpose RF applications in the GNSS L1 band. It operates at a center frequency of 1.575 GHz with a bandwidth of 40 MHz and an insertion loss of 0.9 dB. The component utilizes a 5-SMD surface-mount package with dimensions of 1.4 mm in length, 1.1 mm in width, and 0.7 mm in height. It is compliant with RoHS standards.

Feature Summary

• Utilizes Surface Acoustic Wave technology for precise signal filtering
• Optimized for GNSS L1 band reception with 40 MHz bandwidth
• Compact 5-SMD surface-mount footprint for space-constrained designs

Applications

• GNSS receiver front-end filtering
• GPS module signal conditioning
• IoT device location tracking circuits

Procurement Notes

Verify the specific suffix T2 against the official Abracon datasheet to confirm pinout and tape-and-reel specifications. Ensure compatibility with your PCB footprint design, as the 5-SMD package requires precise soldering alignment. Cross-reference the center frequency and bandwidth requirements with your system architecture to guarantee optimal signal integrity without external tuning components.

Selection Notes

Select this component when a low-profile SAW filter is required for L1 band applications. The 0.9 dB insertion loss offers efficient signal transmission compared to higher-loss alternatives. Consider the 1.4x1.1x0.7 mm package size for dense board layouts. Verify that the 40 MHz bandwidth aligns with your receiver's channel spacing needs to prevent adjacent channel interference.

Part Context

This part belongs to Abracon's lineup of surface-mount SAW filters targeting global navigation satellite systems. It serves as a critical passive component for isolating desired frequencies from noise in GPS and GLONASS receivers. The series is engineered for high reliability in consumer electronics and industrial IoT devices requiring precise frequency selection.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult Abracon technical support or authorized distributors for direct equivalents or pin-compatible alternatives that meet the same 1.575 GHz center frequency and 40 MHz bandwidth specifications.
