The AV103-12LF GaAs IC FET voltage variable attenuator provides
35 dB attenuation range at 900 MHz controlled by a single positive
voltage. The VVA has a linear transfer curve of 9 dB/V slope, with
input and output VSWR better than 2.1:1 over all states. Its attenuation range at 1900 MHz is 33 dB. It operates with supply voltage
of 5 V and control voltage of 0 V to 5 V in a low-cost SOIC-8
package. The RF ports require 100 pF DC blocking capacitors.

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.
