Hyperabrupt Tuning Varactors SMV1232-SMV1237 Features High Capacitance Ratio, C1 V/C3 V = 1.8, C1 V/C6 V = 3.1 Low Series Resistance for Low Phase Noise Multiple Packages SOT-23, SOD-323, SC-70 and SC-79 Designed for High Volume Commercial Applications Full Characterization with SPICE Models Absolute Maximum Ratings Description Characteristic The SMV1232-SMV1237 series of silicon hyperabrupt junction varactor diodes are designed for use in VCOs with low tuning voltage operation. The low resistance of these varactors makes them appropriate for high Q resonators in wireless system VCOs to frequencies beyond 2.5 GHz. The SMV1232-SMV1237 series is fully characterized for capacitance and resistance over temperature. SPICE model is provided.
