TA2604B

Overview

The TST TA2604B is a surface acoustic wave (SAW) filter designed for Bluetooth RF applications. It operates at a center frequency of 2442 MHz with an 84 MHz bandwidth. The component features a low insertion loss of 2.3 dB and is housed in a compact 5-SMD, No Lead package measuring 1.4 x 1.1 mm.

Feature Summary

• Surface acoustic wave technology for RF filtering
• Optimized for Bluetooth communication bands
• Compact SMD footprint for space-constrained designs

Applications

• Bluetooth RF modules
• Wireless communication devices
• Mobile phone baseband circuits

Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and pinout configurations. Ensure compatibility with reflow soldering profiles specified by the manufacturer. Confirm that the 5-SMD no-lead package matches your PCB land pattern requirements before finalizing procurement orders.

Selection Notes

Select this component when designing for Bluetooth 2.4 GHz ISM band applications requiring precise frequency selection. The 2.3 dB insertion loss offers efficient signal transmission. The small 1.4x1.1 mm size is suitable for high-density board layouts where space is limited compared to larger ceramic filters.

Part Context

TST (Tai-Saw Technology) specializes in SAW components for wireless communications. The TA2604B belongs to their RF SAW filter series, targeting mobile and consumer electronics markets. This part supports the growing demand for compact, high-performance filtering solutions in portable Bluetooth-enabled devices.

Replacement Considerations

Check for direct substitutes from other SAW manufacturers offering identical 2442 MHz center frequency and 84 MHz bandwidth. Verify package dimensions and pin assignments to ensure mechanical interchangeability without PCB redesign.
