The AA116-72 is a 1-bit GaAs IC FET digital attenuator in a lowcost package. This attenuator has an LSB of 15 dB. The AA116-72
is particularly suited where high attenuation accuracy, low insertion
loss, and low intermodulation products are required. Typical applications include cellular radio, wireless data, and wireless local loop
gain level control circuits.

Description
J1
DC blocking capacitors (CBL), bypass capacitor (CBP), and biasing resistor must be supplied
externally for positive voltage operation.
CBL = 33, CBP = 39 pF for operation @ 900 MHz.
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.
