SMV1405–SMV1419

Description

The SMV1405–SMV1419 series of silicon abrupt junction

varactor diodes are designed for use in VCOs requiring tight

capacitance tolerances. The low resistance of these

varactors makes them appropriate for high Q resonators

in wireless system VCOs to frequencies beyond 2.5 GHz.

The devices are characterized for capacitance over

temperature. SPICE models are provided.
