SMV1231–SMV1237: Hyperabrupt Tuning Varactors
Features
● _{High capacitance ratio}
● _{Low series resistance for low phase noise}
● _{Multiple packages SOT-23, SOD-323, SC-70 and SC-79}
● _{Designed for high volume commercial applications}
● _{Full characterization with SPICE models}
Description
The SMV1231–SMV1237 series of silicon hyperabrupt junction
varactor diodes is designed for use in VCOs with low tuning voltage
operation. The low resistance of these varactors makes them
appropriate for high Q resonators in wireless system VCOs
to frequencies beyond 2.5 GHz. The SMV1231–SMV1237 series is
fully characterized for capacitance and resistance over tempera-
ture. SPICE model is provided.
NEW Skyworks offers lead (Pb)-free “environmentally
friendly” packaging that is RoHS compliant
(European Parliament for the Restriction of
Hazardous Substances).

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, Electrostatic Discharge (ESD) 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.
