SMV1234-011LF

Overview

The SMV1234-011LF is a silicon hyperabrupt junction tuning varactor diode from the Skyworks SMV123x series, housed in an SOD-323 package with a marking code of DQ. It features a typical capacitance (CT) of 6.28 pF at 1 V reverse voltage and 3.58 pF at 3 V. The device has a minimum reverse voltage (VR) of 15 V and a maximum forward current (IF) of 20 mA. Series resistance (RS) is typically 0.80 Ω at 3 V and 500 MHz. Operating temperature ranges from -55 °C to +125 °C, with storage temperatures up to +150 °C.

Feature Summary

Designed for low tuning voltage Voltage Controlled Oscillators (VCOs)
High capacitance ratio suitable for wide frequency tuning
Low series resistance optimized for high-Q resonators and low phase noise
Packages rated MSL1, compatible with 260 °C lead-free soldering

Applications

Low tuning voltage VCOs
High-Q resonators in wireless system VCOs
High-volume commercial systems

Procurement Notes

Verify component authenticity by checking the DQ marking on the SOD-323 package against official Skyworks documentation. Confirm RoHS compliance and lead-free status via the LF suffix. Ensure handling follows ESD precautions and moisture sensitivity level 1 guidelines during solder reflow processes.

Selection Notes

Select this part when a nominal capacitance near 6.28 pF at 1 V is required for hyperabrupt tuning applications. Compare series resistance values against other SMV123x variants if phase noise performance is critical. Verify that the SOD-323 footprint matches the target PCB layout constraints.

Part Context

The SMV1234-011LF belongs to the SMV123x family of silicon hyperabrupt junction varactors designed for RF and microwave applications. This series includes various capacitance options packaged in SC-79, SOD-323, SOT-23, and SOD-882 formats, all characterized for consistent performance over temperature variations.
