Description
The SMV1705 series are silicon hyperabrupt junction varactor
diodes specifically designed for battery operation. The speci-
fied high capacitance ratio and low R
S
of these varactors make
them appropriate for low noise VCOs used at frequencies in
wireless systems to beyond 2.5 GHz. Applications include low
noise and wideband UHF and VHF VCO for GSM, PCS, CDMA
and analog phones.

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.
