• High capacitance ratio at low reverse voltage
• Packages rated MSL1, 260 °C per JEDEC J-STD-020

Applications

• Low phase noise VCOs in wireless systems
• RF and microwave VCOs
• Phase shifters

Procurement Notes

Verify the specific datasheet version and revision history before procurement, as Skyworks may update product information without notice. Confirm that the SOD-882 package marking DK3 matches your design requirements. Ensure adherence to ESD precautions during handling, as electrostatic discharge can damage the device. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select the SMV2023-004LF when high capacitance values are needed compared to other members of the SMV2019 to SMV2023 series. Its hyperabrupt junction特性 provides a high capacitance ratio, making it suitable for designs requiring wide tuning ranges with low reverse voltages. Consider the 0.45 nH series inductance for RF circuit integration where minimal parasitic effects are critical.

Part Context

The SMV2023-004LF belongs to the SMV2019 to SMV2023 series of hyperabrupt junction tuning varactors. This family includes variants like the SMV2019, SMV2020, and SMV2022, each offering different capacitance ranges and package options such as SC-79, SOT-23, and SOD-323. The series is designed for low phase noise applications in wireless systems, providing consistent performance across various frequency bands.

Replacement Considerations

Direct replacements within the same series include the SMV2022-004LF, which offers similar characteristics but with lower capacitance. Other compatible parts in the SOD-882 package are the SMV2020-040LF and SMV2022-040LF. Verify electrical parameters and package dimensions before substitution to ensure compatibility with existing designs.
