Description
The SMV1142–SMV1148 series of silicon hyperabrupt junction
varactor diodes is specifically designed with an increasing
gamma vs. voltage characteristic. This characteristic will result in
improved VCO frequency-voltage linearity, in comparison to a
conventional hyperabrupt junction varactor. This family of varac-
tors is characterized for capacitance and resistance over
temperature. SPICE models are provided.

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.
NEW
Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
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.
