Feature Summary

• Utilizes Surface Acoustic Wave technology for RF filtering
• Designed as a bandpass filter for wireless applications
• Compact surface-mount construction without leads

Applications

• Wireless RF systems requiring 1.765 GHz filtering
• Mobile communication devices
• RF front-end modules

Procurement Notes

Verify the manufacturer designation TST corresponds to Tai-Saw Technology Co. Ltd. when sourcing. Confirm the specific package variant matches the 6-SMD, No Lead specification. Ensure the center frequency requirement aligns precisely with 1.765 GHz before procurement.

Selection Notes

Select this component for applications necessitating a narrow 30 MHz bandwidth at 1.765 GHz. The 3 dB insertion loss characteristic should be evaluated against system link budget requirements. The small form factor suits space-constrained PCB layouts.

Part Context

This SAW filter belongs to the category of passive RF components used in signal conditioning. It serves to isolate specific frequency bands within wireless transceivers, reducing interference from adjacent channels while maintaining signal integrity in high-frequency operations.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 1.765 GHz center frequency, 30 MHz bandwidth, and 6-SMD package dimensions.
