Description
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.
The AA116-72 is a 1-bit GaAs IC FET digital attenuator in a low-
cost 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 appli-
cations include cellular radio, wireless data, and wireless local loop
gain level control circuits.
Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.

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.
