Procurement Notes

Verify the specific datasheet revision and compliance documentation directly with the manufacturer or authorized distributors. Confirm that the 10-SMD package dimensions and pinout match the target PCB layout requirements. Ensure the RoHS3 status aligns with regional regulatory mandates for the intended deployment environment.

Selection Notes

Select this component when a discrete SAW filter is required for GSM band processing at 170.2 MHz. The 10-SMD form factor supports automated assembly processes. Consider the low-profile height constraint if vertical space within the device chassis is limited. Validate insertion loss and rejection characteristics against system-level link budget requirements.

Part Context

This part belongs to Qualcomm's RF Front-End (RFFE) filter portfolio, which includes various acoustic technologies such as ultraSAW and TC-SAW.
