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.
