• High capacitance ratio for effective voltage-controlled operation

Applications

• Frequency agile microstrip patch antennas
• Voltage-controlled oscillators (VCOs)
• RF phase shifters and tunable filters

Procurement Notes

Verify the specific suffix against official Skyworks documentation to confirm exact electrical tolerances and packaging details. Confirm end-of-life status and availability through authorized distributors prior to procurement planning.

Selection Notes

Select this component when a compact SOD-882 footprint is required for high-frequency tuning. Ensure the circuit design accommodates the specified 15 V reverse voltage limit and utilizes the 0.45 nH parasitic inductance in impedance matching networks.

Part Context

This part belongs to the SMV1234 series of varactor diodes designed for RF tuning applications. It shares the same package and basic electrical characteristics as variants like the SMV1234-040LF and SMV1234-011LF, differing primarily in specific capacitance values or tolerance grades defined by the manufacturer.

Replacement Considerations

Direct substitutes include other Skyworks SMV1234 series variants such as SMV1234-040LF or SMV1234-011LF, provided their specific capacitance ranges align with the design requirements.
