SMV1206-079LF

Overview

The SMV1206-079LF is a single hyperabrupt junction tuning varactor diode manufactured by Skyworks Solutions Inc. It is housed in an SC-79 (SOD-523) surface-mount package designed for very low series resistance applications, such as RF and microwave voltage-controlled oscillators (VCOs). The device features a peak reverse voltage of 22 V and operates within a temperature range of -55°C to +125°C. Key electrical parameters include a capacitance of 4.8 pF at 4 V and 1 MHz, with a maximum capacitance ratio of 5.0 under specified conditions.

Feature Summary

• Hyperabrupt junction design optimized for wide tuning range applications
• Low series resistance suitable for high-frequency RF and microwave circuits
• Single configuration integrated into compact SC-79 surface-mount packaging

Applications

• RF and microwave voltage-controlled oscillators (VCOs)
• Frequency synthesizers requiring precise tuning capabilities
• Phase-locked loops (PLLs) for signal generation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to the availability of counterfeit components in the market. Confirm RoHS compliance status and check for specific lot traceability requirements if mandated by your quality management system. Ensure that the ordering suffix matches the required tape and reel specifications for automated assembly processes.

Selection Notes

Select this component when a hyperabrupt capacitance-voltage characteristic is required for broad frequency tuning ranges in oscillator designs. The low series resistance makes it suitable for high-Q applications where insertion loss must be minimized. Compare the 22 V reverse voltage rating against the maximum expected bias voltage in your circuit to ensure reliable operation without breakdown.
