SMV1417-004 Datasheet | Alpha Industries

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 mercial 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.
