Description
The AV110-73 GaAs IC FET voltage variable attenuator provides
33 dB attenuation range at 1900 MHz controlled by a single
positive voltage. The VVA has a linear transfer curve of 12 dB/V
slope, with input and output VSWR better than 2:1 over all states.
It operates with supply voltage of 3 V and control voltage of 0 V
to 3 V in a low-cost SOT-6 package. The RF ports require 25 pF
DC blocking capacitors.
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 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.
