AFS1575.42S4-T

Overview

The AFS1575.42S4-T is a Surface Acoustic Wave (SAW) filter designed for GPS RF applications at a center frequency of 1.575 GHz. It features a 2.4 MHz bandwidth and 1.5 dB insertion loss. The component operates within a voltage rating of 5 V and maintains a 50 Ohm impedance. It is housed in a compact 6-SMD, No Lead package measuring 3 mm in length and 1.5 mm in width.

Feature Summary

• Utilizes Surface Acoustic Wave technology for precise signal filtering
• Optimized for Global Positioning System radio frequency applications
• Designed for low insertion loss to preserve signal integrity

Applications

• GPS receiver modules
• Navigation systems
• GNSS tracking devices

Procurement Notes

Verify the specific datasheet version for the AFS1575.42S4-T to confirm exact mechanical dimensions and electrical tolerances. Ensure compatibility with the target PCB footprint, as the component uses a 6-SMD no-lead package. Cross-reference the center frequency and bandwidth requirements against the system design specifications before finalizing procurement.

Selection Notes

Select this component when a dedicated SAW filter is required for L-band GPS signals. The 50 Ohm impedance matches standard RF transmission lines. Consider the 1.5 dB insertion loss impact on overall system sensitivity. The small form factor suits space-constrained mobile and handheld electronic designs requiring reliable GNSS reception.

Part Context

This part belongs to Abracon's lineup of surface acoustic wave filters. These components are engineered to isolate specific frequency bands from broader RF spectra. The AFS1575.42S4-T specifically targets the GPS L1 band, providing necessary attenuation for out-of-band interference while passing the desired navigation signal.
