Silicon Hyperabrupt Varactor Diode Chips SMV2019 to SMV2023 Features I High Q for Low Loss Resonators I Low Leakage Current I High Tuning Ratio for Wideband VCOs I SPICE Model Parameters I Small Footprint Chip Design Description Alpha Industries’ product line of silicon hyperabrupt junction varactor diode chips are processed using established ion-implantation technology resulting in low RS wide tuning ratio devices with high Q values. These planar chips have a small outline size (12 x 12 mils nominal) and are fully passivated resulting in low leakage current and high reliability. These varactor chips are intended for assembly in hybrid integrated circuit resonators used in VCOs and analog tuned filters.
