Description

The AV104-12 GaAs IC FET voltage variable attenuator provides

25 dB attenuation range at 900 MHz controlled by a single positive

voltage. The VVA has a linear transfer curve of 5 dB/V slope, with

input and output VSWR better than 1.4:1 over all states. Its attenu-

ation range at 1900 MHz is 22 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 25 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: 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.
