Description
The AA280-25 is a 5-bit, GaAs IC FET digital attenuator in a low-
cost SOIC-16 package. This attenuator has an LSB of 0.5 dB and
a total attenuation of 15.5 dB. The AA280-25 is particularly suited
where high attenuation accuracy, low insertion loss and low
intermodulation products are required. Typical applications
include cellular radio, wireless data, wireless local loop and other
gain level control circuits.
