Description
Alpha Industries’ product line of silicon hyperabrupt junction varactor diode chips are processed using established ion-implantation technology resulting in low RSwide tuning ratio devices with high Q values. These planar chips have a small outline size (12 x 12 milsnominal) 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.

FEATUREs
■ High Q for Low Loss Resonators
■ Low Leakage Current
■ High Tuning Ratio for Wideband VCOs
■ SPICE Model Parameters
■ Small Footprint Chip Design
