SMV1130-079LF

Overview

The SMV1130-079LF is a surface-mount hyperabrupt junction tuning varactor diode manufactured by Skyworks Solutions, Inc. It is housed in an SC-79 package with a series inductance of 0.7 nH. The device features a typical capacitance of 21.2 pF at 1 V reverse bias and achieves a high capacitance ratio of up to 4.50 between 1 V and 9 V. Electrical specifications include a maximum reverse voltage of 26 V, a breakdown voltage of 26 V, and a low series resistance of 0.8 Ω at 500 MHz. Operating temperatures range from -55 °C to +125 °C.

Feature Summary

• Designed for wideband Voltage-Controlled Oscillator (VCO) applications due to high tuning ratios and low series resistance.
• Packages are rated for Moisture Sensitivity Level 1 (MSL1) and withstand soldering temperatures up to 260 °C per JEDEC J-STD-020 standards.

Applications

• Wideband Voltage-Controlled Oscillators (VCOs)
• High-volume, low-cost RF systems

Procurement Notes

Verify the component against official datasheets to confirm electrical parameters such as capacitance tolerance and series resistance. Ensure that handling procedures comply with ESD protection guidelines during assembly. Confirm compliance with RoHS directives and verify the specific package marking matches the ordered part number before integration into production lines.

Selection Notes

Select this component when designing circuits requiring high capacitance tuning ratios within a compact footprint. The SC-79 package offers a balance of low parasitic inductance suitable for S-band frequencies. Evaluate the SPICE model parameters for accurate simulation of circuit behavior under varying reverse bias conditions.

Part Context

This component belongs to the SMV1130 series of hyperabrupt junction tuning varactors. Other variants in the series include the SMV1130-040LF and SMV1130-011LF, which differ primarily in their series inductance values and packaging formats (SOD-882 and SOD-323).

Replacement Considerations

Direct replacements within the same series include the SMV1130-040LF and SMV1130-011LF. These alternatives share identical electrical characteristics but feature different series inductances and package types, requiring layout adjustments.
