Description
The AA113-310 is a 6 bit, single positive control GaAs IC
FET digital attenuator with driver. It is particularly suited
at IF frequencies where high attenuation accuracy, low
insertion loss and low intermodulation products are
required. Typical applications include base station,
wireless data, broadband and wireless local loop gain
control circuits.
