Description
The SMV1405–SMV1413 series of 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.
Performance is guaranteed only under the conditions listed in the specifications table and is
not guaranteed under the full range(s) described by the Absolute Maximum specifications.
Exceeding any of the absolute maximum/minimum specifications may result in permanent
damage to the device and will void the warranty.
CAUTION:
Although this device is designed to be as robust as
possible, ESD (Electrostatic Discharge) can damage
this device. This device must be protected at all times
from ESD. Static charges may easily produce poten-
tials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.
