Description
The AA107-310 is a GaAs FET IC 5 bit digital attenuator
with a serial-to-parallel driver packaged in a 32 leadless
exposed pad plastic package. 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 and RF data and
wireless local loop gain control circuits.
