| Description & Applications | Hyperabrupt Tuning Varactors 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 themappropriate for high Q resonators in wireless system VCOs to frequencies beyond 2.5 GHz. The SMV1231–SMV1237 series is ully characterized for capacitance and resistance over temperature. SPICE model is provided. High capacitance ratio 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 |
