Product Description

Product Overview

The Skyworks SMV123x series are silicon hyperabrupt junction varactor diodes specifically designed for low tuning voltage Voltage Controlled Oscillators (VCOs). These varactors feature low series resistance, making them ideal for high-Q resonators in wireless system VCOs operating at frequencies exceeding 10 GHz. The series is characterized for capacitance and resistance over temperature, offering a high capacitance ratio and MSL1 rating for robust performance in high-volume commercial systems.
