TA2294A

Overview

The TA2294A is a Surface Acoustic Wave (SAW) bandpass filter manufactured by TST, designed for wireless RF applications. It operates at a center frequency of 915 MHz with a bandwidth of 26 MHz and an insertion loss of 3.6 dB. The component utilizes a 5-SMD, No Lead package with dimensions measuring 1.1 mm x 0.9 mm and a maximum height of 0.022 inches. It is specifically engineered for the North American unlicensed ISM band.

Feature Summary

• Compact surface-mount form factor optimized for space-constrained designs
• Engineered specifically for the North American unlicensed ISM band
• Surface acoustic wave technology for RF signal filtering

Applications

• Wireless communication systems
• North American ISM band equipment
• RF front-end modules

Procurement Notes

Verify the specific packaging option required, as the manufacturer offers Tape & Reel (TR), Cut Tape (CT), and Digi-Reel® variants. Confirm that the 5-SMD No Lead package aligns with your PCB footprint requirements. Ensure the component status remains Active for current production needs. Cross-reference the 915 MHz center frequency specification against your system design parameters to guarantee compatibility.

Selection Notes

Select this component when a minimal footprint is critical for the application, given its 1.1 mm x 0.9 mm dimensions. It is suitable for designs targeting the 915 MHz frequency range with a 26 MHz bandwidth requirement. Consider the 3.6 dB insertion loss characteristic in link budget calculations. The SMD package type dictates the assembly process and soldering profile requirements for the manufacturing line.
