The AA226-87 is a 4-bit, single positive control GaAs IC FET digital attenuator. It requires DC blocking capacitors, positive supply
voltage (VS) and four individual positive bit control voltages
(V1–V4). The AA226-87 is particularly suited where high attenuation accuracy, low insertion loss and low intermodulation
products are required. Typical applications include base station,
wireless data and wireless local loop gain control circuits.

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.
