Description
The SMV1405–SMV1413 series of bare die, epoxy and hermetic
packaged silicon abrupt junction varactor diodes is 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.
NEW
Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.

CAUTION:
Although these devices are designed to be robust, ESD
(Electrostatic Discharge) can cause permanent damage.
Static charges may easily produce potentials of several
kilovolts on the human body or equipment, which can
discharge without detection. Industry-standard ESD
precautions must be employed at all times.
