TA2247A

Overview

The TST TA2247A is a surface acoustic wave (SAW) filter designed for wireless RF applications. It operates at a center frequency of 1565.5 MHz with an 81 MHz bandwidth and exhibits a typical insertion loss of 3.7 dB. The component is housed in a compact 6-SMD, no-lead package measuring 3.0 x 3.0 mm with a maximum height of 1.40 mm. It supports a maximum input power of 15 dBm and withstands a maximum DC voltage of 3 V. The device functions within a temperature range of -40°C to 105°C and complies with RoHS standards.

Feature Summary

• Utilizes surface acoustic wave technology for precise signal filtering in radio frequency circuits.
• Features a compact SMD footprint suitable for space-constrained mobile and wireless designs.
• Complies with RoHS specifications and supports lead-free soldering processes.

Applications

• Wireless communication systems
• Radio frequency signal processing
• Mobile device front-end modules

Procurement Notes

Verify the manufacturer part number TA2247A against official TST documentation to ensure authenticity. Confirm that the received components match the specified 6-SMD package dimensions and electrical parameters. Check for RoHS compliance markings and ensure storage conditions adhere to MSL1 requirements to maintain component integrity prior to assembly.

Selection Notes

Select this SAW filter for applications requiring a 1565.5 MHz center frequency and 81 MHz bandwidth. Ensure the design accommodates the 3.0 x 3.0 mm surface mount package and thermal limits up to 105°C. Validate that the system input power does not exceed 15 dBm to prevent device damage during operation.

Part Context

The TA2247A belongs to the TST SAW filter series, which provides passive filtering solutions for RF signals. These components are engineered for high selectivity and low insertion loss in wireless infrastructure. The specific model targets frequencies around 1.5 GHz, distinguishing it from other variants in the family that operate at different center frequencies such as 1257.0 MHz.

Replacement Considerations
