SMV1129 - Hyperabrupt Junction Tuning Varactors

General Description

The SMV1129 and SMV1139 silicon hyperabrupt junction varactor diodes are designed for use in VCOs requiring low resistance.

The low resistance of these varactors makes them appropriate for high Q resonators in wireless system VCOs to frequencies beyond 2.5 GHz.

Key Features

  • I High Q I Low Series Resistance for Low Phase Noise I Multiple Packages SOD-323, SC-79 and SC-70 I Designed for High Volume Commercial.
