SMV1129-079LF

Hyperabrupt Junction Tuning Varactor


The SMV1129-079LF 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.
