Overview
The SMV1245-011LF is a hyperabrupt junction tuning varactor diode manufactured by Skyworks Solutions, Inc. It features an SOD-323 surface-mount package with a series inductance (LS) of 1.5 nH and series resistance (RS) of 2.0 Ω at 500 MHz. The device operates within a temperature range of -55°C to +125°C and has a reverse breakdown voltage of 26 V. At 1 V and 1 MHz, the typical capacitance is 4.9 pF, with a maximum of 5.4 pF. The capacitance ratio (CTR) is 4.20 when comparing 1 V to 3 V conditions.
Feature Summary
- Designed for very low series resistance applications in RF and microwave circuits
- Features high tuning ratio suitable for wideband voltage-controlled oscillators
- Compliant with RoHS standards and halogen-free
Applications
- Wideband RF and microwave VCOs
- Electronically tunable filters
- Impedance matching networks
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the presence of the 'HL' marking on the SOD-323 package to ensure correct identification. Check datasheet revisions and environmental compliance documentation prior to procurement to align with current manufacturing standards.
Selection Notes
Select this component for designs requiring low series resistance and high capacitance ratios in compact SMD form factors. Ensure the operating voltage remains below the 26 V breakdown limit. Verify that the 1.5 nH parasitic inductance fits the target frequency response requirements compared to lower-inductance alternatives like the SMV1245-079LF.
Part Context
This part belongs to the SMV1245 series of hyperabrupt junction tuning varactors from Skyworks Solutions. The series includes variants such as the SMV1245-079LF, which utilizes an SC-79 package with different parasitic characteristics. These devices are engineered for high-volume commercial applications requiring reliable performance in RF tuning environments.
Replacement Considerations
The SMV1245-079LF serves as a functional alternative within the same series, offering similar electrical characteristics but housed in an SC-79 package with reduced series inductance (0.7 nH). Designers must account for package dimension differences and layout adjustments when substituting between these two specific part numbers.
FAQ
What is the marking code for the SMV1245-011LF?
