SMV1413-079LF

Overview

The SMV1413-079LF is a silicon abrupt junction tuning varactor diode from the Skyworks SMV1405 to SMV1430 series, designed for Voltage Controlled Oscillators (VCOs) requiring tight capacitance tolerances. It features low series resistance suitable for high-Q resonators in wireless systems operating above 10 GHz. The device is housed in an SC-79 package with a typical series inductance of 0.7 nH. Electrical specifications include a maximum reverse voltage of 30 V and a forward current rating of 20 mA. At 0.5 V reverse bias, the typical capacitance is 7.4 pF, while at 30 V it drops to 1.77 pF. The total capacitance ratio (C0/C30) is typically 4.2.

Feature Summary

• Designed for high-Q resonators in wireless system VCOs
• Low series resistance supports low phase noise performance
• Characterized for capacitance stability over temperature

Applications

• High volume commercial systems
• Voltage Controlled Oscillators (VCOs)
• Wireless system resonators

Procurement Notes

Verify component authenticity against official Skyworks documentation prior to assembly. Confirm that the SC-79 package marking matches the datasheet specification for the SMV1413 variant. Ensure handling procedures adhere to industry-standard ESD precautions to prevent damage during transport and soldering processes.

Selection Notes

Select this component when a higher capacitance value is required compared to other members of the SMV1405 to SMV1430 family. The SMV1413 offers a typical C0 of 7.4 pF, distinguishing it from lower capacitance options like the SMV1405 or SMV1430. Verify that the SC-79 package dimensions and 0.7 nH series inductance align with the specific RF layout requirements.

Part Context

The SMV1413-079LF belongs to the SMV1405 to SMV1430 group of plastic-packaged abrupt junction tuning varactors. This series shares common electrical characteristics such as a 30 V reverse voltage limit and 250 mW power dissipation capability. The -079 suffix specifically denotes the SC-79 surface mount package configuration.

Replacement Considerations

Other members of the SMV1405 to SMV1430 series may serve as alternatives if different capacitance values are acceptable. Variants such as SMV1405-079LF or SMV1430-079LF share the same package and absolute maximum ratings but offer distinct capacitance ranges.
