Description
The SMV1231–SMV1237 series of silicon hyperabrupt junction varactor diodes is 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 SMV1231–SMV1237 series is fully characterized for capacitance and resistance over temperature. SPICE model is provided.
