Product Description

Product Overview

The Skyworks SMV1247-SMV1255 series comprises silicon hyperabrupt junction varactor diodes specifically engineered for Voltage Controlled Oscillators (VCOs) requiring low tuning voltage operation. These varactors are characterized for capacitance and resistance across temperature ranges, offering a high capacitance ratio of 12 typical (C0.3V/C4.7V). They are designed for high-volume commercial systems and are rated MSL1, 260 C per JEDEC J-STD-020, with Skyworks Green compliance.
