TA2550A

Overview

The TA2550A is a Surface Acoustic Wave (SAW) filter manufactured by TST, designed for Global Positioning System (GPS) radio frequency applications. It operates at a center frequency of 1.1918 GHz with a bandwidth of 55 MHz and an insertion loss of 4 dB. The component utilizes a 5-SMD, no-lead package configuration, suitable for compact electronic designs requiring precise signal filtering in navigation systems.

Feature Summary

• Engineered specifically for GPS RF signal processing
• Utilizes Surface Acoustic Wave technology for efficient filtering
• Compact surface-mount design for space-constrained applications

Applications

• Global Positioning System receivers
• Satellite navigation modules
• Mobile device location services

Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and thermal characteristics. Ensure compatibility with the target PCB footprint for the 5-SMD no-lead package. Cross-reference official TST documentation for any recent manufacturing updates or environmental compliance certifications relevant to the production batch.

Selection Notes

Select this component when a dedicated SAW filter is required for the L1 GPS band around 1.1918 GHz. Consider the 55 MHz bandwidth relative to the receiver's signal requirements. Evaluate the 4 dB insertion loss impact on overall system sensitivity compared to alternative filter technologies.

Part Context

TST specializes in RF SAW filters for mobile communications and navigation. The TA2550A belongs to their portfolio of components supporting satellite positioning standards. This part addresses the need for high-selectivity filtering in modern GNSS front-end architectures.

Replacement Considerations

Consult official TST documentation for verified substitute part numbers. Do not assume functional equivalence with generic SAW filters without verifying center frequency, bandwidth, and package dimensions against the original specifications.
