Product Description
Skyworks SMV1247-SMV1255 Series: Hyperabrupt Junction Tuning Varactors
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, offering a high capacitance ratio of 12 typical (C0.3V/C4.7V). Designed for high-volume commercial systems, they are rated MSL1, 260 C per JEDEC J-STD-020 and are available as Skyworks Green products, compliant with all applicable legislation and halogen-free.
