The Skyworks SMV1405 to SMV1430 series are silicon abrupt junction varactor diodes designed for Voltage Controlled Oscillators (VCOs) in wireless systems requiring tight capacitance tolerances. These varactors offer high Q and low series resistance, making them suitable for high-Q resonators in wireless system VCOs operating at frequencies above 10 GHz. They are characterized for capacitance over temperature and are available in various package options.
