SMV1702-011LF

Overview

The SMV1702-011LF is a silicon hyperabrupt junction tuning varactor diode designed for battery-operated wireless systems. It features a single configuration in an SOD-323 package with an internal series inductance of 1.5 nH. The device operates within a reverse voltage range up to 10 V and supports forward currents up to 20 mA. Electrical specifications include a typical capacitance of 90 pF at 0.1 V, decreasing to 22 pF at 4 V, yielding a capacitance ratio of 4.0. Series resistance is typically 1.25 Ω at 470 MHz. Operating temperatures extend from -55 °C to +125 °C.

Feature Summary

• Hyperabrupt junction design optimized for high capacitance ratio and low series resistance
• Small footprint SOD-323 surface-mount package compatible with standard reflow processes
• Integrated 1.5 nH series inductance for improved RF performance

Applications

• Low-noise and wideband UHF and VHF Voltage Controlled Oscillators (VCOs)
• High-volume, low-voltage VCO designs

Procurement Notes

Verify the specific datasheet revision against current Skyworks documentation before finalizing procurement. Confirm that the Green™ marking indicates lead-free RoHS compliance. Ensure ESD protection protocols are strictly followed during handling, as the component is classified as a Class 0 Human Body Model device. Check moisture sensitivity level requirements if storage conditions have been compromised.

Selection Notes

Select this component when a high capacitance ratio is required for wide tuning ranges in VHF and UHF applications. The integrated 1.5 nH inductance simplifies circuit layout by reducing external parasitic effects. Verify that the maximum reverse voltage rating of 10 V aligns with the system's biasing requirements. Consider the thermal dissipation limits of 250 mW for power handling capabilities.
