AA116-72, AA116-72LF: GaAs IC 1-Bit Digital Attenuator
15 dB LSB 4 MHz–2 GHz
Features
l 3 V control
l Low loss
l Low-cost SOT-5 plastic package
l A vailable lead (Pb)-free and RoHS-compliant, MSL-1 @ 260 °C
per JEDEC J-STD-020
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.

DC blocking capacitors (Cbl), bypass capacitor (Cbp), must be supplied externally for positive
voltage operation.
Cbl = 33 pF, Cbp = 39 pF for operation @ 900 MHz.
Cbl = 100 nF, Cbp = 100 nF for operation @ 0.004–0.05 GHz.
