Description
The AA104-73 is a 1-bit, GaAs IC FET digital attenuator in a low-cost
SOT-6 package. This attenuator has up to 32 dB total attenuation. The
attenuator requires two lines of voltage control. The AA104-73 is partic-
ularly suited where high attenuation accuracy, low insertion loss, and
low intermodulation products are required. Typical application is as a
sixth bit value for the AA260-85 and AA101-80. A total attenuation of
63 dB in 1 dB steps can be obtained by combining the two attenuators.
NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
