TA2248A

Overview

The TA2248A is a Surface Acoustic Wave (SAW) filter manufactured by Tai-Saw Technology (TST). It operates at a center frequency of 1.223 GHz, designed specifically for GPS RF applications. The component features an insertion loss of 3.5 dB and a bandwidth of 54 MHz. It is housed in a compact 6-SMD, No Lead package with dimensions of 3.00mm x 3.00mm, suitable for surface mount assembly.

Feature Summary

• Designed for Global Positioning System radio frequency signal filtering
• Utilizes Surface Acoustic Wave technology for high performance
• Compact surface mount package for space-constrained designs

Applications

• GPS receiver front-end modules
• Satellite navigation systems
• Wireless communication devices requiring L-band filtering

Procurement Notes

Verify the specific datasheet version from Tai-Saw Technology to confirm electrical parameters and mechanical drawings. Ensure compatibility with the target PCB footprint, as the component uses a leadless SMD package. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm that the 1.223 GHz center frequency aligns with the specific GPS band requirements of the end application.

Selection Notes

Select this component when a dedicated SAW filter is required for GPS signals around 1.223 GHz. Consider the 3.5 dB insertion loss and 54 MHz bandwidth against system sensitivity requirements. The SM3030-6PAD package size should be evaluated against available board space. Compare performance metrics with alternative BAW or LC filters if higher selectivity or lower loss is needed for the specific design.

Part Context

Tai-Saw Technology specializes in SAW and BAW components for wireless communications. The TA series includes RF SAW filters targeting GPS, GLONASS, GALILEO, and BeiDou applications. This model fits within their portfolio of surface acoustic wave devices used in mobile phones, base stations, and positioning equipment.

Replacement Considerations

Check for direct substitutes from Tai-Saw Technology with similar center frequencies and package types. Verify that any replacement maintains the 1.223 GHz operating point and compatible 6-SMD form factor. Consult official TST documentation for approved pin-compatible alternatives.
