Abrupt Junction Tuning Varactors SMV1405–SMV1419 Features s High Q s Low Series Resistance for Low Phase Noise s Multiple Packages SOT-23, SOD-323, SC-70 and SC-79 s Designed for High Volume Commercial Applications s SPICE Models are Available Description The SMV1405–SMV1419 series of silicon abrupt junction varactor diodes are 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.
