Applications

• General purpose RF filtering

Procurement Notes

This component is officially marked as obsolete by the manufacturer. Verification of availability should focus on secondary market sources or legacy inventory rather than direct production channels. Confirm exact lot dates and storage conditions when sourcing from non-original distributors to ensure reliability.

Selection Notes

Engineers requiring this specific 1.21GHz SAW filter must account for its discontinued status. Design reviews should prioritize identifying equivalent active components that meet the 77MHz bandwidth and 4.2dB insertion loss specifications. Verify pin compatibility and thermal characteristics if substituting with newer generations.

Part Context

Part of the Qualcomm RF front-end filter portfolio, specifically within the B1677 series. These filters are designed to address RF design challenges in wireless connectivity devices. The product line leverages acoustic technologies to provide filtering solutions for various communication standards.

Replacement Considerations

As an obsolete part, no official direct substitutes are listed in public documentation. Engineers should evaluate alternative SAW filters from Qualcomm or other manufacturers that match the 1.21GHz center frequency and 8-SMD footprint requirements.
