The SMV1142–SMV1148 series of silicon hyperabrupt junction varactor diodes are specifically designed with an increasing gamma vs. voltage characteristic. This characteristic will result in improved VCO frequency-voltage linearity, in comparison to a conventional hyperabrupt junction varactor. This family of varactors is characterized for capacitance and resistance over temperature. SPICE models are provided.
