Procurement Notes

This component is officially scheduled for obsolescence and has been discontinued by the manufacturer. Availability is limited to existing stock or last-time buys from authorized distributors. Verify current status directly with suppliers before procurement planning. Do not assume ongoing production support. Check datasheet revision history for any final design changes prior to integration into new hardware designs.

Selection Notes

Select this part only if legacy compatibility with the SA614A family is required. The integrated RSSI and muting features simplify circuit design for specific RF applications. Ensure the 25MHz IF bandwidth meets system requirements. Consider that the component is obsolete; alternative solutions may be necessary for long-term product sustainability. Verify pinout compatibility if replacing older variants within the same series.

Part Context

The SA614AD/01,118 belongs to the SA614 series of RF ICs. It represents an improved version of the SA604, offering higher IF bandwidth. The device is classified under RF Misc ICs and Modules. It is designed for low-power consumption in portable and fixed wireless applications. The 16-SOIC package facilitates automated surface-mount assembly processes.

Replacement Considerations

No public confirmed substitute part numbers are available. The component is marked as obsolete. Engineers must evaluate functional equivalents from other manufacturers or newer generations within the NXP portfolio. Verify electrical parameters and pin compatibility when selecting alternatives.
