SMV1129 Datasheet | Alpha Industries

Features I High Q I Low Series Resistance for Low Phase Noise I Multiple Packages SOD-323, SC-79 and SC-70 I Designed for High Volume mercial Applications I SPICE Models are Available Description The SMV1129 and SMV1139 silicon hyperabrupt junction varactor diodes are designed for use in VCOs requiring low resistance. The low resistance of these varactors makes them appropriate for high Q resonators in wireless system VCOs to frequencies beyond 2.5 GHz.
