Procurement Notes

Verify the specific ordering suffix to confirm packaging type, such as tape and reel or cut tape, as these affect handling but not electrical function. Confirm the manufacturer source directly through authorized distributors or the original equipment manufacturer's official channels to ensure component authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a SAW filter is required for the 1.6505 GHz band within wireless infrastructure or portable devices. Ensure the design accommodates the 6-SMD footprint and the specified thermal operating range. Compare insertion loss and bandwidth specifications against system requirements to verify compatibility with adjacent circuit stages and overall signal integrity needs.
