SMV1413-000 Chip

Abrupt Junction Varactor Diode Chip


The SMV1405–SMV1413 series of bare die, epoxy and hermetic packaged silicon abrupt junction varactor diodes is designed for use in VCOs requiring tight capacitance tolerances. The low resistance of these varactors makes them appropriate for high Q resonators in wireless system VCOs to frequencies beyond 2.5 GHz. The devices are characterized for capacitance over temperature. SPICE models are provided.
