The AA226-87 is a 4 bit, single positive control GaAs IC

FET digital attenuator. It requires DC blocking capacitors,

positive supply voltage (V ) and four individual positive bit

control voltages (V –V ). The AA226-87 is particularly

suited where high attenuation accuracy, low insertion loss

and low intermodulation products are required. Typical

applications include base station, wireless data and

wireless local loop gain control circuits.
