TA0289A

Overview

The TA0289A is a Surface Acoustic Wave (SAW) bandpass filter manufactured by TST. It operates at a center frequency of 159.0125 MHz with a bandwidth of 6.025 MHz. The device exhibits an insertion loss of 2.8 dB and supports a maximum input power level of 10 dBm. It is housed in a compact 10-SMD, No Lead package measuring 7.0 x 5.0 mm with a maximum height of 2.00 mm. This component is designed for wireless RF applications requiring precise signal filtering.

Feature Summary

• Utilizes Surface Acoustic Wave technology for efficient radio frequency signal processing
• Provides bandpass filtering characteristics to isolate specific frequency bands
• Engineered for surface mount assembly to facilitate automated manufacturing processes

Applications

• Wireless communication systems
• Radio frequency signal conditioning
• RF front-end modules

Procurement Notes

Verify the exact datasheet revision, currently identified as Rev. 2.0, against supplier documentation to ensure parameter alignment. Confirm that the 10-SMD No Lead package dimensions match your PCB footprint requirements. Ensure the operating environment remains within the specified electrical ratings, particularly the 10 dBm input power limit, to maintain device integrity and performance stability during deployment.

Selection Notes

Select this component when a fixed center frequency of 159.0125 MHz is required for wireless applications. The 6.025 MHz bandwidth defines the signal pass range, while the 2.8 dB insertion loss impacts system gain budget calculations. Consider the physical dimensions of the 7.0 x 5.0 mm package for spatial constraints in dense circuit board layouts.
