TA0391A

Overview

The TA0391A is a surface acoustic wave (SAW) band-pass filter manufactured by TST. It operates at a center frequency of 1747.5 MHz with a bandwidth of 75 MHz. The device utilizes SAW technology to provide high selectivity and low insertion loss, typically around 4 dB. It is housed in a compact 6-SMD, no-lead package measuring 3.00 mm x 3.00 mm with a maximum height of 1.40 mm. This component is designed for wireless RF applications requiring precise frequency filtering.

Feature Summary

• Utilizes surface acoustic wave technology for signal processing
• Provides high selectivity for radio frequency signals
• Designed for low insertion loss performance
• Compact surface-mount package suitable for space-constrained designs

Applications

• Wireless communication systems
• RF front-end modules

Procurement Notes

Verify the specific datasheet version from Tai-Saw Technology Co., Ltd. to confirm electrical parameters such as insertion loss and return loss. Ensure the 6-SMD package dimensions match your PCB footprint requirements. Confirm RoHS compliance status if required for your manufacturing process. Cross-reference the part number TA0391A with official manufacturer documentation to avoid counterfeit components.

Selection Notes

Select this component when a 1747.5 MHz center frequency and 75 MHz bandwidth are required for wireless applications. Consider the 6-SMD package size for assembly compatibility. Evaluate the 4 dB insertion loss against system link budget requirements. Ensure the operating temperature range meets environmental specifications. Compare performance metrics with alternative SAW filters if tighter bandwidth or lower loss is needed.

Part Context

Tai-Saw Technology Co., Ltd. specializes in RF SAW filters for wireless communications. The TA0391A belongs to their portfolio of band-pass filters designed for modern mobile and wireless standards.
