TA2240A

Overview

The TST TA2240A is a Surface Acoustic Wave (SAW) filter designed for GPS RF applications. It operates at a center frequency of 1.5425 GHz with a bandwidth of 35 MHz and insertion loss of 4 dB. The component provides high attenuation of 58 dB and is housed in an SMD3030-8P package. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Surface Acoustic Wave technology for precise signal filtering
• Optimized for Global Positioning System radio frequency applications
• Compact surface-mount design suitable for space-constrained PCB layouts

Applications

• GPS receiver front-end modules
• Satellite navigation system filters
• RF signal processing circuits requiring 1.5 GHz band filtering

Procurement Notes

Verify the manufacturer part number TA2240A against official TST documentation to ensure authenticity. Confirm that the package designation matches SMD3030-8P or 8-SMD No Lead specifications. Check for RoHS compliance status as indicated in the datasheet. Ensure the supplier provides valid traceability records for electronic components.

Selection Notes

Select this component when a SAW filter with a 1.5425 GHz center frequency is required for GPS signals. Consider the 35 MHz bandwidth and 4 dB insertion loss characteristics for circuit compatibility. Verify that the SMD3030-8P footprint fits the board layout constraints. Ensure the operating temperature range meets the environmental requirements of the target application.

Part Context

This component belongs to the SAW filter category manufactured by TST. It is specifically engineered for radio frequency applications in the L-band spectrum. The device utilizes acoustic wave propagation principles to achieve sharp frequency selectivity. It is distinct from LC filters or ceramic resonators due to its specific surface acoustic wave construction.
