Description
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.
NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
