SMV1147-011LF

Overview

The SMV1147-011LF is a silicon hyperabrupt junction tuning varactor diode from the Skyworks SMV114x series, housed in an SOD-323 package with a marking code of GY. It features a low series resistance of 0.55 Ω typical at 3 V and 500 MHz, and a quality factor of 150 typical at 3 V and 50 MHz. The device supports a maximum reverse voltage of 12 V and operates within a temperature range of -55 °C to +125 °C. Capacitance values are specified as 60.65 pF at 1 V, 38.58 pF at 3 V, and 22.58 pF at 6 V.

Feature Summary

Frequency linear design utilizing an increasing gamma versus voltage characteristic for improved Voltage-Controlled Oscillator (VCO) frequency-voltage linearity compared to conventional hyperabrupt junction varactors.

Applications

High volume commercial systems

Procurement Notes

Verify component authenticity by checking the GY marking on the SOD-323 package against official datasheet documentation. Confirm lead-free status through RoHS compliance markers. Ensure proper ESD handling protocols are followed during storage and assembly due to Class 0 Human Body Model sensitivity ratings.

Selection Notes

Select this component when high capacitance ratios and specific linearity characteristics are required for VCO applications. Verify that the SOD-323 package dimensions and thermal dissipation limits align with the target circuit board layout and operating environment constraints.

Part Context

This part belongs to the SMV114x family of silicon hyperabrupt junction varactor diodes designed for commercial applications. The series includes variants like SMV1142 through SMV1148, differentiated primarily by their capacitance ranges and package types such as SC-79 or SOD-323.
