Procurement Notes

Verify component authenticity through authorized Skyworks channels or certified distributors. Confirm that the specific order matches the SMVA1248-079LF designation and packaging requirements. Ensure handling procedures comply with ESD protection standards during storage and assembly.

Selection Notes

Select this component when designing VCOs requiring low tuning voltages and high capacitance ratios. Verify that the 15 V reverse voltage rating meets the circuit's peak operating conditions. Ensure the SC-79 package dimensions align with the target PCB layout constraints.

Part Context

This part belongs to the SMVA series of hyperabrupt junction varactors from Skyworks Solutions. It is specifically engineered for automotive applications, distinguishing itself from standard commercial variants through its qualification to AEC-Q101 standards and optimized performance characteristics for in-vehicle electronic systems.

Replacement Considerations

No direct public substitute part numbers are documented for this specific model. Designers should evaluate alternative hyperabrupt varactors by comparing key electrical parameters such as capacitance ratio, reverse voltage ratings, and package compatibility.
