Product Description
Product Overview
The Skyworks SMV1247-SMV1255 series are silicon hyperabrupt junction varactor diodes specifically designed for Voltage Controlled Oscillators (VCOs) requiring low tuning voltage operation. These varactors are characterized for capacitance and resistance over temperature, offering a high capacitance ratio of 12 typical (C0.3V/C4.7V). They are suitable for high-volume commercial systems and are rated MSL1 at 260 C, compatible with both leaded and lead-free soldering processes.
