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.
