TA0281A

Overview

The TA0281A is a Surface Acoustic Wave (SAW) band-pass filter manufactured by TST. It operates at a center frequency of 915 MHz with a bandwidth of 26 MHz and insertion loss of 2.2 dB. The component utilizes a 6-SMD, no-lead package with dimensions of 3.0x3.0 mm and a maximum height of 1.42 mm.

Feature Summary

• Surface Acoustic Wave technology for RF filtering
• Band-pass configuration optimized for specific frequency ranges
• Compact surface-mount design suitable for space-constrained applications

Applications

• Wireless Local Area Networks (WiFi)
• Bluetooth communication systems
• Global Navigation Satellite Systems (GNSS)

Procurement Notes

Verify the exact datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Ensure the ordering suffix matches the required packaging format, as standard listings may vary in reel or tape specifications. Confirm lead times and availability through official supply chain channels to avoid counterfeit components.

Selection Notes

Select this component when a 915 MHz center frequency with 26 MHz bandwidth is required for RF signal conditioning. The 3.0x3.0 mm SMD package offers a balance between performance and board space efficiency. Consider the 2.2 dB insertion loss specification in link budget calculations for low-power wireless applications.

Part Context

This part belongs to TST's SAW filter portfolio, which covers various RF applications including IoT, LTE, and automotive sensors. The TA series typically addresses general-purpose filtering needs in consumer electronics and industrial equipment, providing reliable signal integrity in crowded RF environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs if considering alternative manufacturers, as SAW filter characteristics are highly specific to frequency and bandwidth requirements.
