SMV1232-079LF

Overview

The SMV1232-079LF is a silicon hyperabrupt junction tuning varactor diode from Skyworks Solutions, designed for low tuning voltage VCOs and high-Q resonators in wireless systems. It operates at frequencies over 10 GHz with a maximum reverse voltage of 15 V and forward current of 20 mA. The device dissipates up to 250 mW and functions within an operating temperature range of -55 °C to +125 °C. Typical capacitance values include 2.86 pF at 1 V and 0.94 pF at 3 V, yielding a capacitance ratio of approximately 3.05. Series resistance is typically 1.50 Ω at 3 V and 500 MHz.

Feature Summary

Hyperabrupt junction design optimized for low tuning voltage operation
Low series resistance characteristics suitable for high-Q resonators
Capable of supporting VCO applications at frequencies exceeding 10 GHz

Applications

Low tuning voltage Voltage Controlled Oscillators (VCOs)
High-Q resonators in wireless system VCOs
High-volume commercial RF systems

Procurement Notes

Verify the specific datasheet revision against the manufacturer's official documentation before implementation. Confirm that the SC-79 package marking matches the required cathode indicator. Ensure handling procedures strictly follow ESD precautions and moisture sensitivity level requirements during assembly.

Selection Notes

Select this component when a capacitance ratio near 3.0 is required alongside low series resistance for phase noise optimization. Verify that the 15 V reverse voltage rating aligns with the circuit's maximum bias conditions. Consider the -55 °C to +125 °C operating range for environmental compatibility.

Part Context

This part belongs to the SMV123x series of hyperabrupt junction varactors. The series includes variants such as the SMV1231 through SMV1237, which offer different capacitance ranges while sharing similar low-resistance performance profiles. All members are characterized for capacitance and resistance over temperature.
