Description
The SMV1800-079LF is a silicon hyperabrupt junction varactor
diode specifically designed for battery operation.The specified
high capacitance ratio and low RS of this varactor make it
appropriate for low noise VCOs used in wireless systems to
frequencies beyond 2.5 GHz. Applications include low noise
and wideband UHF and VHF VCO for GSM, PCS, CDMA and
analog phones.

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