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.
